S C H E M A T I C F I L E R V1.1 ---------------------------------- By Jeff Cutcher 01/26/88 (A SHAREWARE PROGRAM) Schematic Filer Page 1. SHAREWARE This program is sharware. I find that many programs that are shareware turn out to be as good or even better than commercial soft- ware. Many of the people who make these programs available for you work very hard to make the best. I am starting to do my best to make programs available to you, without having you to pay $40 to $300. So if you find this program very useful and you want to support shareware, I appreciate it if you send a donation. Now most sharware programs are from $15 to $40. I think that is a very good price range for software. So, if you find that this program is of use to you, I ask you to please send $15 with the form below. This program has a special feature that takes use of my program 'IC Data Book', if you do not have a copy of this, please check the appropriate item below to recieve a copy of it. If you do request 'IC Data Book' please send an additional $10, $5 will be for postage and handling, and the other $5 for the program and 30 files. Jeffrey L. Cutcher 174 Lehigh St. Brick, NJ 08724 Schematic Filer Page 2. Schematic Filer allows you to literally draw the schematic in memory using a window. The middle of the screen acts like a window moving across a large area while using the arrow keys to scroll left, right, up, or down. The main purpose of this program is to allow you to have various schematics on disk storage for easy access. The looks of any schematic you draw or view will not be professional. The reason is because you will be using the keyboard and the graphics that are displayed when using the CONTROL KEY along with the keys. The schematics will not be in HI-RES form. So even though they will be vague drawings, they will be suitable enough. I find that this program will be valuable to those people learning electronics now. In the course of study, labs will require to set up simple and sometimes complex circuits. With this program you are able to put these schematics on file for future reference. Using this along with 'IC Data Book' will give you a powerful tool in the field or learning process of electronics.

Miscellaneous Information ------------------------- This program was written in Turbo Pascal and there are some limitations. The working area you have for your schematics will consist of 62,500 characters. When saved, this number will appear in the directory for file length. The program will check the available space left on the current drive to assure that at least 63k is present, if not an error message will occur. This program allows you to copy, move, and save blocks. The block can be up to 100 characters across, and 100 characters down, which is roughly 10k. Now the purpose of this size is because you will really only be using it to move or save individual parts, like chips for example. Most of your blocks will be small, but you can go 100 across and 100 down. A feature I find useful is being able to load in 'IC Data Book' files and have that chip put into the schematic. The chip you request will be loaded into the block memory. Then you just go to the area on the schematic and place it there. The chip will print out vertically along with its pin numbers and pin functions. Another feature is being able to make a parts list. This has a separate menu. This allows you to put in memory 1000 parts with their values. Then those parts get saved in a file. If more than 1000 parts are needed, you can append an additional 1000 to the file, and keep on appending if necessary. Once the file is created, you specify the filename in the menu of the schematic pro- gram. Then while viewing the schematic, you have access to any part on the schematic that you have entered in the file. For example, lets say on a schematic you see 'R001'. You use the appropriate command in the VIEW mode. Then you type in the part 'R001' then the program searches for 'R001' in the file. If a match is found, that value of that part will be displayed. Two example schematics have been made by me in order for you to get an idea on how to go about making a schematic. The first one is not really a TRUE schematic because it doesn't give pin numbers ect. But is a good example. The second one I made took use of the 'IC Data Book' command. And you'll see how a chip prints out in that form by looking at that schematic. The first example I just told you is called 'FCOUNT.SCH' and its parts list filename is 'FCOUNT.PRT'. The second example is called 'DISPLAY.SCH' and its parts list filename is 'DISPLAY.PRT'. Now the extensions are not given when a schematic or parts list is saved. '.SCH' and '.PRT' are just ones I made up. You can use whatever extensions you wish. Schematic Filer Page 4. The Menu -------- This program contains ONE menu. I find it easier to work with. A program is not too user friendly when all the commands have to be memorized. So all MAIN functions will be done through this menu. The menu screen contains THREE sections. The first section is the letter you type to execute that function. Then next to the letter is the function to be executed. Then next to that is a small explanation of that function. You'll find in the third section the explanations are in REVERSE lettering. The word(s) that are NOT in REVERSE mode are special. They inform you of the present schematic filename, the parts list filename, the number of increments in VIEW mode, and the preset path/directory. Right now I will explain EVERY function of the MENU, but specifics will be found in their appropriate section of this manual. The MENU contains 12 functions. They are: - A Get Schematic. - B VIEW Schematic. - C Make a New Schematic. - D Clear Map. - E Change the MOVE value. - F Edit/Continue Schematic. - G SAVE Schematic. - H Parts List. - I Set Parts List Filename. - J Change Drive/Directory. - K Goto Utilities. - Z EXIT Program. Option 'A' - Gets a schematic from the current directory and loads it into memory. You will be prompted for the filename. ** Option 'B' - Puts you into VIEW mode where you use the cursor keys to scroll through the schematic. The VIEW commands are in effect. Option 'C' - This command clears the work area and puts you into EDIT mode. EDIT commands are in effect. Option 'D' - Simply, this command clears the work area. Option 'E' - This command allows you to specify the number of increments the scrolling effect has when VIEWING. If you set this at 5, then while in VIEW mode any way you scroll will go 5 characters in that direction. You can enter a number from 1 to 50. Option 'F' - This puts you into EDIT mode without clearing the work area. Main use would be for making a large schematic in several days. Just load the file and start where you left off. Or this can be used to change items in the schematic or get certain parts and save them. Option 'G' - This commands SAVES the current work area (schematic) to the current directory. You will be asked for a filename. If the filename exists, you will be prompted to continue or stop. ** Option 'H' - Puts you into the parts list sub-menu.(THREE OPTIONS) Option 'I' - Allows you to set the parts list filename. For VIEW mode only. Schematic Filer Page 5. Option 'J' - Allows you to change the DRIVE and/or DIRECTORY. Option 'K' - SAVES variables and exits to DOS. * Option 'Z' - EXITS program and returns to DOS. NOTE: After exiting most likely COMMAND.COM will have to re-loaded. It will search on the drive it is configured for, usually drive A. So if your working directory or even the directory you loaded SC.COM from is other than A:, then you'll have to put in your system disk, or any disk containing COMMAND.COM in drive A:. To select an option simply press the appropriate key and then ENTER. The options that clear the work area will always advise you FIRST before the actual clearing occurs. * NOTE: When using this feature, the DATA directory, move variable, schematic and parts list filename are saved. The VERY next time you run SC.COM, the program will load in the variables and load the schematic you were working on. REMEMBER to put in all appropriate disks first. This mainly concerns two drive systems. ** NOTE: When loading and saving schematics, you will FIRST be prompted to answer [Y]es or [N]o. The phrase you will see is: "Use FILENAME: ?" then you answer yes or no. If you answer yes then that filename will be used. If not you will be asked to type in a filename. FILENAME will be the current filename of the schematic. Upon first booting up, 'ABCDEFGH.123' will be the filename. Do not use that, answer [N]o and put in your own filename. Schematic Filer Page 6. V I E W M O D E ----------------- VIEW mode is used when you want to view a schematic. The main purpose of this is when building the circuit or even troubleshooting. After selecting option 'B' in the menu, the VIEW screen will appear. It consists of many different elements. The main three are the windows. The top window is where the schematic VIEWING takes place. The middle window is just a one line window that shows the command keys of VIEW mode. The last and final window is where input/output occurs. This is where the program outputs messages to you, and also where you type in information. Their are 5 commands in VIEW mode. They are [G]oto X,Y, [P]arts List, [S]earch String, F9, and the '+' key. Simply press the appropriate key and the command will execute. The 'G' command allows you to goto anywhere in the schematic work area. After pressing 'G' you will be asked for an X coordinate. Type a number from 1 to 193 then press ENTER. Then you will be asked for the Y coordinate. Type a number from 1 to 241 then press ENTER. If the numbers you type are valid the program will take you to that location. 'P' allows you to search for a part number on the disk. After pressing 'P' you will be asked for the part identification. For example R001, c001, IC001, Q001, ect. After you type the identification press enter. The program will then search for it in the filename you specified in the menu. If the filename is not found, and error message will occur. If the part isn't found you will be advised. If all goes well, the part that corresponds to the identification will be printed in reverse video. Just press any key to continue. 'S' command searches for a string both vertically and horizontally. Once a match is found, you will be put into that location of the schematic. After hitting 'S' type the string and then ENTER. The further into the map the string is, the longer it will take to find. If you for some reason want to abort the search, just hit any key, and you will return to VIEW mode. When using the 'S' and 'P' commands type EXACTLY what you want at the prompt. Lower case and Upper case letters are NOT treated equally. For example if you had an 'IC001' and 'C001' then you will get wrong information. What I mean by that is, if you want to 'S'earch for 'C001' and the program finds 'IC001' first, you will be put there instead, because 'C001' is part of 'IC001'. So in my examples you will see all capacitors as 'cxxx' and all chips as 'ICxxx'. xxx stands for a three digit number. I use three significant digits because of the same reason. 'IC1' will be found in 'IC100', 'IC11', 'IC12' and so on. Also if you searched for 'C1' it would be found in ALL of the ones just mentioned. This ONLY goes for the 'S'earch command. So as you see, it may be a good habit to identify all parts with three digits, unless you are using more than 999, then use four places. When you press the 'F9' key the commands for the mode you are in will be put into memory, and you can then scroll through them individually. After they are loaded, use the up and down arrow keys to scroll through them. When you have reached the LAST command, the down arrow will have no effect. The same goes for the first command, if you are at the first command, the up arrow will have no effect. This does not enable you to execute commands from this, it is just sort of a HELP feature. After you are done viewing the commands, press the '+' key to return to your current mode. Finally, when you press the '+' key in VIEW mode, you will be sent back to the menu, OR if you previously came from EDIT mode, then you will be sent there. The most IMPORTANT keys are the arrow keys. Use the UP, DOWN, LEFT, and RIGHT arrow keys to scroll the schematic. Remember too, depending on what you have the increment set for will depend on how far the schematic scrolls every push of the arrow key. Schematic Filer Page 7. E D I T M O D E ----------------- Edit mode has many commands in it. Function keys 1 through 10 are used. When in EDIT mode whatever key you type other than a command will go to the screen. This means all letters, numbers, special characters, and CONTROL characters. The commands are: F1- Returns you to the schematic filer menu. F2- Sets Top-Left corner (X,Y) of the CAPTURE block. F3- SAVES current capture. F4- Sets Bottom-Right (X,Y) of the CAPTURE block. F5- LOADS a capture block from disk. F6- Puts defined block into memory. (CAPTURE block) F7- Get IC Data Book file, which loads into CAPTURE block. F8- Place CAPTURE block at current (X,Y) location. F9- Get EDIT mode commands for reference. (HELP) F10- FILL current defined block with SPACES. (ERASES block) HOME- Puts cursor at beginning of line. If cursor is already at the begining then it will be placed at the upper-left corner. END - Puts cursor at end of line. If cursor is already at the end then it will be placed at the lower-right corner. ENTER-Places you in VIEW mode. ALL VIEW mode commands go in effect. After pressing '+' you will be sent back to EDIT mode. When making your schematic use the arrow keys to move up, down, left, or right. When your cursor reaches an edge of the window, further movement will scroll the schematic in the direction you are going. When typing a character the cursor will advance one space to the right. If you're at the right side of the window, no more characters will be placed until you move the screen over more. You can move the cursor freely over characters without corrupting them. To remove a character put the cursor over that character and hit the SPACE bar. The DELETE key has NO effect. The CAPTURE block has been mentioned but not explained. Now it will be. The capture block is used to save a section of the schematic to either move it to another location or save it to disk. When moving a block, there is NO effect on the original. To start the process you first have to define the block.You first set the upper-left corner coordinates. Place the cursor to that position and then press the F2 key. Now place you cursor at the bottom-right corner and then press the F4 key. Now your coordinates are set. Next you press the F6 key. This saves the block to memory. If there is an error in the coordinates or the block is too big then an error message will occur. The block can be 100 characters across(horizontally) and 100 characters down (vertically). That is the maximum, which is 10,000 characters. After pressing F6 and no error message occurs, then the block is saved in memory. Now the X and Y coordinates are still present so you can press F10 to delete that block on the schematic, or you can press F3 to save it to disk. You can also load in a block from disk by pressing F5. After your CAPTURE block is all set then you move the cursor to the position of where you want the block to be placed. After you do that, press F8 and suddenly your block appears on the schematic. You can keep moving and placing as long as you want. BUT, once any of the block command keys are pressed, the current CAPTURE block is ERASED. Also note that when setting the X and Y coordinates you are NOT restricted to just the window, you can for example set the top-left corner, then press ENTER, [G]oto another area, press '+' to return to the EDIT mode, and then set your bottom-right X,Y coordinates. As long as it is equal to or less than 100 you will have no problem. The same holds true for placing blocks. After saving a block to memory 'F6', you can go anywhere in the schematic and place that block. The program however will not place it if you are to close to the VERY end of the schematic or at the very bottom. If you place the block towards the middle or edge of the window, and there is enough room, the block will be put in the schematic. It may not be all seen at once, but as you scroll you will see the whole block is present. Schematic Filer Page 8. To further explain what I mean by enough room is, if you create a block of lets say 50 by 50 characters. Of course when you place it on the schematic it will run off the window, because the window is only 57 characters across and 9 characters down. So if you place the block within bounds, then it will be put there, but you'll have to scroll to see the whole thing. NOTE, within bounds I mean, the whole schematic work area is 250 by 250. If your block is 50 by 50 there is NO way to place it when your X coordinate is greater than 200. The same goes for the Y coordinate. When using 'F10', you do NOT have to hit 'F6' after you set the coordinates. 'F6' is for putting the block in memory. When using 'F10' there is no limit to the X and Y values you set. But, if you attempt to capture a block of over 100 and error will occur. To determine the amount of characters you have set, take the bottom-right corner coordinates minus the top-left corner coordinates. If those two numbers are both less or equal to 100 you will have no error, in CAPTURING that is. Schematic Filer Page 9. P A R T S L I S T ------------------- The parts list is just a simple file containing all the components and their values that make up the schematic. To create a parts list you type 'H' and then ENTER at the schematic menu. Then you will see a 3-option menu: 1 - Create a parts list. 2 - Add more parts to existing list. 3 - Exit. When first making a parts list file for any schematic you choose option 1. You will then type in every part identification along with its value, or small note. When entering them, first type in the EXACT identification, then press ENTER. Then you will be asked for the 'PART>'. Here you type the note or value. For example: 1> R001 PART> 100 ohms. 2> R002 PART> 150 ohms. 3> c001 PART> 2200 micro Farads. 4> DONE PART> And so on. IF you have a large parts list you can enter a few at a time. Then at your next session, you would select option 2, to append any additional parts to the existing file. To stop entering parts at the 'x>' prompt type 'DONE' then hit ENTER. Then at the 'PART>' prompt just hit ENTER. You will be asked then to [S]ave or [E]xit. If you exit then those parts are lost. If you reach 1000 parts, the program will halt, and display the above message. When you [S]ave them, all the parts will be put in the file. If more than 1000 are needed in the file, just append them. NOTE: above I mentioned 'x>', this is where x equals any number from 1 to 1000. That is where you type 'DONE' to stop. Finally, option 3 will take you back to the schematic filer menu. Now that the file is created, you can use the 'P' command in VIEW mode. Before you do that you must set the filename in the schematic filer menu. Press 'I' and then ENTER. You will then be asked for the parts list filename. Type it in and then ENTER. Now if your schematic is not loaded in memory, do that next. Once your schematic is in memory type 'B' to view it. As you come across a part you want to know about, hit 'P'. You will then be asked for the part identification. Type EXACTLY what you see, all UPPER and lower case letters. For example 'R001' or 'c100'. Then if it is found in the file, the value will be displayed in reverse video. As mentioned on page 4, I said ONE menu. Going into the parts list is a sub-menu, but the main idea I was getting acrossed was that this program executes functions from ONE menu. If you ever need to edit or change something in a parts list file, you can simply load it into a simple editor. The first item is the part identification and the second item is the part value. You can also if you wish, make the parts list from an editor. JUST remember, the identification comes first, and the part value comes second. Schematic Filer Page 10. D I S K O P E R A T I O N S ----------------------------- This section is just to make you aware of the file handling of this program. There four different disk operations that can be preformed. They are 1) Loading a schematic, 2) Saving a schematic, 3) Setting the working directory, and 4) Making a parts list. Whenever a schematic gets saved you will be informed if the file already exists. If it does, you will have the option to [C]ontinue or [S]top. If you stop then nothing will happen to the file already on disk and nothing will have happened to the schematic in memory. If you continue then the file will be ERASED and then the schematic in memory will be saved. Upon booting up schematic filer the program will remember what directory you are in. Then you have the option of changing the directory for your DATA. If this directory is changed, all schematics and part lists will be saved and loaded from that directory. You DO NOT have to change the directory if you hit 'F9' for help, because these files should be on the directory that 'SC.COM' is in. Then the program will automatically change directories, retreive the help file, and then change the directory back. Also all capture block files will be loaded and saved from the directory you specify. As mentioned earlier after you exit the program, COMMAND.COM will most likely have to be re-loaded. If so, I assume most systems are configured to look up COMMAND.COM in drive A:\. What I suggest you do is put the files 'SC.COM', 'VIEW.CMD', and 'EDIT.CMD' in the drive that your computer searches on for COMMAND.COM. Then include the COMMAND.COM file with those. If you have a hard drive and the computer searches for COMMAND.COM on drive C:\ then you should have no problem because all your work will be done on drive C:. The reason I mention this is because if you only have two drives and you for some reason put your DATA disk in drive A, and your program disk in drive B, then after exiting it will not find COMMAND.COM on drive A, UNLESS you have it on your data disk. So I suggest you put COMMAND.COM on the program disk in the drive COMMAND.COM is supposed to be in, most likely A:, unless you have a hard drive. Schematic Filer Page 11. V I E W AND E D I T S C R E E N S ---------------------- The VIEW and EDIT screens are EXACTLY the same. The only difference is the commands. You will notice 2 sets of coordinates. At the top are X and Y coordinates. They pertain to the upper-left corner of the window, (HOME). The other set, located on the right, are CX and CY. They are the CURSOR X and Y coordinates, NOT the SCREEN (X,Y) but the schematic (X,Y). CX and CY can range from 1-249, the X coordinate ranges from 1-193, and the Y coordinate ranges from 1-241. When in VIEW mode both sets will be equal, because the cursor is sent to the HOME position. When in EDIT mode, however, X and Y give you the HOME coordinates while CX and CY give you the EXACT position of where your cursor is at in the schematic work area. In between the X and Y coordinates will be an indicator telling you if your in EDIT mode or VIEW mode. Also the arrow that lights up will signify what direction you are going in. IC Data Book Files ------------------ One feature I find very useful is being able to use IC Data Book files. These files are created by my program IC Data Book (CHIPS.COM). Each file contains all the data for that particular chip. Schematic filer extracts only the pinouts and then puts them into a pictorial of a chip. Then it is saved in the CAPTURE block. To get a chip from an IC Data Book file press F7 in EDIT mode. Then you will be asked for the drive/directory that the file is in. After you type that in, the program will search for the file, extract the pinouts, and create the chip in the CAPTURE block. Then use your arrow keys to put the cursor wherever you want. Then press F8. The chip will then be placed in the schematic. The chip will remain in the CAPTURE block until a block command key is hit. You may also after getting the chip, save it. Then all you have to do is use the block command for loading, F5. Of course, if you do not have IC Data Book than this feature is not of ANY use to you. So be sure to include the extra $10. I think it will be well worth it. Schematic Filer Page 12. V A R I A B L E S P E C I F I C S ----------------------------------- This section will give the specifics on the variables. -Schematic work area..............................1 - 249 x 1 - 249 characters. -Filenames, Directories,and any string inputs........Maximum of 20 characters.* -CAPTURE Block....................................1 - 100 x 1 - 100 characters. -X value...............................................................1 - 193. -Y value...............................................................1 - 241. -CX value..............................................................1 - 249. -CY value..............................................................1 - 249. -Schematic Window across.........................................57 characters. -Schematic Window down............................................9 characters. -Parts in List....................................1000 in memory at one time.** * Since filenames can only be up to 12 characters (ffffffff.fff) long, I made the maximum string input to 20 characters. I dont think a directory of OVER 20 characters is needed either. If you are going to make your own directories I suggest you call them something like 'C:\SC' and 'C:\SC DATA'. I used the C: because most to all directories are made on hard drives. ** 1000 parts can be entered in memory at ONE time. BUT, you can keep appending up to 1000 parts to an existing file. For example one file could have 30 parts, while another may contain 5000 parts. So I don't think you will be entering schematics with over 1000 parts, but if for some reason you do, over 1000 parts can be in a file. Schematic Filer Page 13. T H E E X A M P L E S ----------------------- I have made two examples for you to see how a schematic is drawn and viewed. The two examples are, with their parts list, 'FCOUNT.SCH' - 'FCOUNT.PRT', and 'DISPLAY.SCH' - 'DISPLAY.PRT'. FCOUNT is a frequency counter circuit and DISPLAY is a simple circuit that reads a numeric keypad and prints the appropriate number pressed. By looking at these examples you will get a good understanding of how to build your own schematics. I use the minus sign mostly for drawing lines. You'll also notice that I use the equals sign for corners. DISPLAY takes advantage of the IC Data Book files. You'll be able to see how the chips look on the schematic. It took me awhile to do these schematics and I find that it was well worth it. I hope you think the same. Enjoy the program and remember, support SHAREWARE. If you find this program useful please send $15 to: Jeffrey Cutcher 174 Lehigh Street. Brick, NJ 08724 P.S. If you have any questions I can be contacted via Compuserve, my number is [71071,263]. Schematic Filer Page 14. U P D A T E Version 1.1 -------------------------- A couple of things were added. One, I changed the cursor. The cursor now has two modes. In normal mode the cursor is NORMAL. When in this mode the cursor will not advance when you type a character. To TOGGLE between modes press ALT-C. In the second mode, the cursor will be SOLID. When in this mode, the cursor will advance in the direction previously taken, every time you type a character the cursor will advance UP, DOWN, LEFT, or RIGHT. If you wanted to go UP, press the up arrow key. Then, whenever a key is hit, that key will be placed and the cursor will be advanced. The other addition pertains to the BLOCK commands. After defining a block you can hit F10 to erase it. Then you may place the block where you want. BUT, once you place the block, you CAN NOT erase what you defined. In VERSION 1.0, the coordinates would stay no matter what. So, if you defined a block, and placed it at different sections of the schematic, and then you accidentally hit F10, ZAP!, the block you copied from is gone. If you find any more BUGS or you have suggestions, please leave me mail on COMPUSERVE or send it to me. Schematic Filer Page 15.
