bBaseII Version 5.32 by Robert Bromley May 3, 1992 If you would like to make a print-out of this documentation, I would recommend that you print out the file "bBaseII_printme.doc". It will make a neater print job. This file is the same, except it has all of those messy ANSI codes removed.

What it does is store, sort, sift, and search for information, (but it won't dial your telephone). Once a database has been loaded from disk, all modifications are done in RAM:, and will NOT be permanently saved until the database is Saved to disk. This can be done using the Menu, the Function Keys, or upon Quiting. All functions of bBase may be accessed from Menus. Most also have keyboard equivalents for the hard-core CLIers. It multi-tasks extremely well, as it does not burn up CPU time while not actually performing operations. bBaseII was written in HiSoft BASIC Version 1.05, and compiled using the HiSoft BASIC Professional compiler. 1.2 Feature Summary Some of the features of bBaseII are: - Fully intuitionized. - Very straightforward and easy to use. - Uses a fast (for a BASIC program) shell-sort algorithm. - Incremental or decremental sort, on any field. - Search in any (or all) field(s). - Optionally display entire database, or a filtered list, a screenful at a time. - Print out a record, a filtered list, or the whole database, in many different formats. - Prints mailing labels. - Optionally disable the "Save to Disk" option to prevent accidental alteration of the database. - Well-behaved in a multi-tasking environment. 1.3 Hardware Requirements Database programs tend to gobble up large amounts of memory. bBaseII is no exception. Since bBaseII opens on it's own screen, and reserves memory to hold a database in RAM:, it requires about 375K of memory to run properly with a FULL 600 record database. This could be reduced if the maximum number of records was reduced, but it was necessary to hard-code in something, so that's what I picked. I would not recommend running bBase on a basic 512 Kb machine. 1.4 Software Requirements The "arp.library" will have to be in your libs: directory, because bBase uses the ARP file requester - but everyone should have that there by now, right? 1.5 Restrictions - 9 fields per record. - bBaseII: 600 records, or a database of approximately 100K, whichever comes first. - bBaseII50K: (Refer to Section 7.2 - "The Companion Program"): 600 records, or a database of approximately 50K, whichever comes first. NOTE Be careful when the database size exceeds 100K (or 50K for bBaseII50K) - it will exit ungraciously if it runs out of memory. This is the main reason I limited the maximum number of records. Refer to Section 7.3 - "The Low Memory Warning". 1.6 Copyright bBaseII is Copyright (1991) by Robert Bromley. All rights are retained by the author. Use of this program is at your own risk and discretion. This program is freeware, and may be distributed free of charge. Nominal charges for copy media only, are permitted. 1.7 Starting bBaseII From the Workbench; just click on the icon. From the CLI; usage is: Run bBaseII [-s] [-fFilename!] Including the -s switch will start bBase with Saves Disabled. Including the -f switch will automatically load the requested database file. If using this switch, do not leave a space between "-f" and the filename, and be sure to add an exclamation point (!) immediately after the filename. Also, do not include the ".bbase" extension. IE. : Run bBaseII -s -fDF0:Files/Recipes! NOTE Naturally, when using the -f switch, no exclamation points are allowed in the filename path. 2 THE REQUESTERS 2.1 The ARP File Requester The requester used when asking for a file to Load or Save is the standard ARP file requester. 2.2 The String Requester This requester is used for general input. It has full editing capabilities. It may be blanked at any time by pressing <Alt-X>. Any time this requester is open, pressing <Esc> will close it. 3 THE CURSOR KEYS 3.1 If the String Requester is NOT Open: Pressing the Cursor Up key will take you directly to the First Record. The Cursor Down key displays the Last filled Record. The Cursor Left key shows the Previous numerical Record, and the Cursor Right key will show the Next numerical Record. You can also move through the records using the mouse (Refer to Section 4 - "THE SCREEN GADGETS"). The VERY last record is always blank, which is where additional records may be entered. This blank record is accessed through the "Add" Menu item, or by pressing F10. 3.2 If the String Requester IS Open: Whenever you are in Edit Mode (ie. the string requester is open, so that you may Enter or Change data), Cursor Left/Right moves the cursor within the gadget, while Cursor Up/Down moves through the fields. 4 THE SCREEN GADGETS The Information Box at the bottom of the screen contains a / \ gadget that looks something like that shown at the right. | | This gadget represents the Cursor Keys, and you can move <== G ==> about the database using these gadgets and the mouse | | instead of the Cursor Keys, if you so desire. \ / Clicking on the Up Arrow will take you directly to the First Record. Clicking on the Down Arrow will take you to the Last filled Record. The Left Arrow will show the Previous numerical Record to the one currently displayed, and the Right Arrow will show the Next Record. If the Last Record is currently displayed, this will take you to the blank record, where a new record may be entered, although this is more easily accomplished by using the "Add" Menu item, or by pressing F10. Clicking on the "G" in the center of the arrows will bring up the string requester, asking for the number of a record to "Goto". After entering a legal number, the requested record will be displayed. 5 The PROGRESS BAR When time consuming actions are being performed, ie. Loading, Searching, Saving, Sorting, etc., a "progress" bar will appear to assure you that "something is happening", and visually display to you just how the job is progressing. 6 THE MENUS bBase operation is best described by the operation of the Menus. The keyboard equivalents, where applicable, are shown along with the Menu Titles. 6.1 Project Menu 6.1.1 Create a New Database (F1) This will bring up the ARP file requester, asking for a name for your new database. Any filename of 20 characters or less will do. The requester will then ask how many fields the new database will require. There may be up to 9 fields in each database. I would recommend that you always ask for the whole 9 fields, even if you don't expect to use them all. The extra memory is negligable, but the flexability is enormous - and you cannot ask for more later. You are then asked for the TITLES of each field of the database. Each field title may be a maximum of 19 characters long. A "(1)" will appear, along with the string requester. Enter the title of your first field, ie. Last Name, First Name, Company, Address, or anything else. When it is correct, hit <Return>, and a "(2)" will appear on the next line with the requester. Enter the title of the second field. Enter all the field titles in this manner. The screen will now show all the field titles, an Instruction Box, the File Name as first entered, a blank data area, and the Record Number, which at this point will be "1". The data requester will now appear in the first field of the first record, ready for you to enter data. Enter the data. NOTE Double quotes are not accepted in any data field, as that would mess up the alignment of all the following fields. Single quotes are OK. A data entry may be a maximum of 46 characters long. When it is correct, hit <Return> again, and the requester will move to the second field. When all fields are complete, the Record Number will indicate "2", and the data area will go blank, (because there is not yet a Record Number 2). Hitting <Return> again will start the process of entering data into the second record. Complete all records in this manner. In this version there is a limitation of 600 records. If you had been working on an existing database, and it had been altered, you would have been asked if you wanted to Save it before creating a new one. 6.1.2 Open an Existing Database (F2) If you have previously created a database, and the "Database_name.bbase" file is stored on a disk, then use this item to access that database. If you are working on an existing database, and it has been altered, you will be asked if you want to Save it before loading another. Enter the path to the database file in the requester, and that database will be retrieved and shown on screen. Only files having the extension ".bbase" will be initially displayed. Use the Cursor keys or mouse to move about the database. Refer to Section 3 - "THE CURSOR KEYS", and Section 4 - "THE SCREEN GADGETS". While a record is displayed, the Information Box will instruct you to press "<Return> to Change Data". Do so, and the requester will appear in the first field, with that field's data. <Return> or Cursor Up/Down to the field you want to change, and make the changes. At this point, you may either <Return> through all fields, or press F10 to exit the Editing Mode. The altered record will be displayed. NOTE ANY time you are in Edit Mode, whether Entering, Changing or Searching for data, pressing F10 will exit the Edit Mode, and use the data shown when you exited. 6.1.3 Display Entire Database If you want to quickly glance at more than one record at a time, this will open a full-sized screen, and display the first 70 or so characters of ALL records, one record to a line. The display will pause after each 23 records - click on "Next Page" or press any key to see the next screenful, or click on "Prev Page" to see the preceding page. Click on "Cancel", or Press <Esc> to leave this function. If you see a record you want to examine in detail, just click on it. You will then exit the Display window, and return to the Main Screen, with the requested record displayed. 6.1.4 Display Matching Records This works the same as the previous item, except that ONLY those records that matched the most recent Search pattern, at the time the search was made, are displayed. (Refer to Section 6.3 - "Search Menu"). 6.1.5 Save the Current Database (F3) If the database has been altered since last saved, it will be Saved to disk under the current filename, after confirmation. The file will have the extension ".bbase" automatically appended. If it has NOT been altered, you will be so informed, and given the oportunity to abort the Save. 6.1.6 Save As You will be prompted for a name to Save the database. NOTE Do NOT include the ".bbase" extension at this time. It will be appended automatically. 6.1.7 About The usual stuff. 6.1.8 Quit <Esc> If the database has been altered, you will be asked if you want to Save it before Quiting. 6.2 Sort Menu You may sort the records in the database based on the data in any field. The Sort routine is very efficient for a BASIC program. It will sort 200 records in less than 10 seconds on a standard A2000. As the database size increases, naturally it tends to slow down. 6.2.1 Incremental Sort (F4) The requester will ask which field you want to sort on. The records will be incrementally sorted on that field, and Record Number 1 of the new list will be shown. 6.2.2 Decremental Sort (F5) Same as above, but records are sorted and displayed from Z-A, or 9-0. 6.3 Search Menu 6.3.1 Select Search Criteria (F6) The requester will appear in the first field of a blank record. <Return> or Cursor Up/Down down to the field that contains the data you want to search for. Enter the search string in that field. A search string may be entered in more than one field. When all the criteria has been entered, <Return> through all the fields, or press F10. All records that match ALL the search criteria will be displayed, one by one. When a record is found, you may Print it, Cancel the search, Continue searching, or Review all the records that match that Search pattern. (Refer to Section 6.1.4 - "Display Matching Records"). Search is NOT case dependent. 6.4 Change Menu 6.4.1 Field Titles Use this item to change the Template, ie. the Titles of your fields. The NUMBER of fields may not be changed. The data itself is unaffected by this procedure. 6.5 Print Menu 6.5.1 Displayed Record (F8) This item will first ask how many fields are to be printed, and then in which column position, from 1 to 80, to start printing (in case you want to print a mailing label, or directly onto an envelope). It will then send all characters of the requested number of fields of the currently displayed record to the PRT: device. 6.5.2 Select Print Options (F9) Opens the Print Options Window from which various formats of hardcopy print-outs and mailing labels may be chosen. Refer to Section 7.4 - "The Print Options Window". 6.6 Add Menu 6.6.1 A Record (F10) Positions you at the last (empty) record, with the input requester open, ready for you to enter data into the first field. Use the <Esc> key to back out if you arrived here by mistake. 6.7 Delete Menu 6.7.1 Displayed Record <Del> After confirmation, the record currently displayed is Deleted. 7 OTHER FEATURES 7.1 The "Disable Save" Option As a simple security device, mainly as a guard against someone accidentally altering or erasing data, I have added an option which will disable the ability to save database changes to disk. To disable Saves, simply press "Alt - S" simultaneously. The titlebar will briefly inform you that Saves are disabled, and now any attempt to Save the database to disk will be circumvented. In this case, upon Quiting, a requester will ask if you want to Save the database (as usual). If you select "Save", a second requester will inform you that the Save option has been disabled. To Save the database, at the next requester, "Do you Really want to Quit?", select "Cancel", re-enable Saves, and Quit again. If you are running bBase from the CLI, using the "-s" flag on the command line will start bBase with the Saves already disabled. The "Alt - S" combination will toggle between Save Enabled and Save Disabled. The titlebar message will keep you informed of the current status as it changes. 7.2 The Companion Program - bBaseII50K I am including in this package a companion program (bBaseII50K) for those users who are having memory problems while running bBaseII. bBaseII50K is identical to bBaseII except that it reserves about 100K less memory for operation, and has a database limit of about 50K. If anyone should need a database of more than 600 records, and have the memory to support it, no problem - just let me know! 7.3 The Low Memory Warning When bBaseII is run, it reserves about 200K of memory, (bBaseII50K is less) to use for database storage in RAM, arrays, etc. No matter how much RAM your computer has, this is all that is available to bBase! When a database is first loaded (and only then), bBase will check the available memory left in the program pool. If the memory available to bBase is less than 2K, this means that you have a humungous database of over 100K, and only another 5-10 records may be added before the program will crash. In this case, you will be advised of the situation. Press any key to cancel the warning. The recommended action is: 1. If you are using bBaseII50K, start using bBaseII. 2. If you are using bBaseII, delete some old records. 3. Give me a call. We can get you a larger version. 4. Upgrade from bBase to dBase. NOTE If you are loading a new database after having just finished work on another, it is possible get get a false warning here. If you know your database size is within limits, I think you can safely disregard the warning in this circumstance. 7.4 The Print Options Window Choosing "Select Print Options" (from either the Print Menu, or by pressing F9) opens the Print Options Window. All selections in this window are made using the mouse. At the top, there are gadgets to select either "Print All Records" or "Print Matching Records". Print All Records will do just that. Print Matching Records will print all records which matched the most recent Search pattern, at the time the Search was made. Another gadget, "Bold", allows you to select either Bold or Normal print styles. This gadget is a toggle. At the bottom are gadgets labeled "Cancel", "Help" and "Print!". "Cancel" is self-explanitory. "Help" opens a Help Window which explains the terms used in the Print Options Window, so this information is not included here. "Print!" will print the selected records using the selected format, (assuming your printer is turned on). 7.4.1 Hardcopy Print-outs Database print-outs can be obtained in these formats: Adjacent Single Line - Pica Aligned Single Line - Pica Adjacent Single Line - Elite Aligned Single Line - Elite Adjacent Single Line - Condensed Aligned Single Line - Condensed Block, 2 across Block, 3 across Super Space Saver These are explained in the Help Window, but try them all, and see which one (or more) best suits your needs. Along the top of the Data Area are 4 white pixels. These pixels will align with the data entry cursor at the 24, 25, 38 and 43 character positions. As some of the above print-outs are truncated to these number of characters (Refer to the Help Window), they are a guide to indicate that the data beyond will not be printed when some print options are selected. 7.4.2 Mailing Labels Mailing labels of 15/16 inch, and 1 7/16 inch, in 1-across roll type, and 2 or 3-across sheet type are all supported. If you have selected a mailing label option in the Print Options Window, when you click on "Print!" another window will open, asking whether your labels are 1, 2 or 3-across, and how many fields of your database you want printed on the label. Once this information is received, the printing operation will start. If you tell bBase you want, for example, 4 fields printed, then the first 4 fields will be printed, in numerical order. It is the users responsibility, if this function is used, to organize the database in such a manner that the proper information is printed. Due to the size constraints of the labels, there are limits on the number of characters of each field, and the number of fields, that this function will print. This information is in the Help Window. I confess that this is my first attempt at this sort of thing. To date, I have never used a mailing label in any program. It was, however, requested by several individuals, and I have done my best to implement it, although doing so has increased the size of bBase considerably. As always, I am open to any and all suggestions. 8 EXAMPLE DATABASE There is an example database included in this package. Everyone uses the Name and Address example, so I opted for something different. The file "Recipes.bbase" is a sample database showing one way of keeping track of recipes, without having to re-type them all. It merely shows where they can be found when needed. With this database you can Sort the recipes by Name, Catagory, or anything else. You can Search for all recipes containing a listed ingredient, recipes you have already served to given people, or just the location of the recipe if you have forgotten which of your 647 recipe books it is in. I have found this to be very useful. 9 CREDITS My thanks to Peter Keegan, of Harvard, MA; Bobby Foreman, of West Sacramento, CA; James Withgott of Orland Park, IL, David Prothero, of Centralia, WA; Reinhard Pfluger, of Mannheim, Germany; and Brad Kane, of Palmdale, CA, for taking the time to write in and suggest some of the improvements to bBase, and to Edward Shaw, of Lexington, KY, for his support of bBaseII. I know the program still far from perfect. If anyone else out there is actually using this thing, I would appreciate some constructive criticism. If writing, be sure to mention which version of bBase you are using. Name and address in "About". Hope someone finds this useful. Bob 10 REVISION HISTORY Version 1: First release - May 1991 Version 2: Internal - Added F10 shortcut to quit editing. - Added <Esc> to return directly to program. - May now cursor up/down through fields while editing. - Added the ability to specify a database on the command line. - Added <Esc> to Quit via keyboard. - Added the "Add a Record" menu item. - Bug fixes. Version 3: Internal, September 1991 - Added the "Display Entire Database" and "Display Matching Records" menu items. - Add "Print Matching Records" menu item. - Changing the maximum number of records was causing crashes. Hard-coded maximum at 600 records, and alloted memory accordingly. - Added the -s and -f command line options. - Changed colors to make the screen more readable. - Added the Progress Bar. - Changed the sort algorithm from Bubble to Shell. Much faster. - More bug fixes. Version 4: Internal, October 1991 - Can now go directly to a record from the "Display Entire Database" and "Display Matching Records" windows, by clicking on it. - Field Titles now stay neater after being changed. Version 5.0: 77172 bytes. Released November 1991 - The Sort algorithm is now case independent. - Added the Low Memory Warning. - Bad bug: If the database was sorted decrementally, on a field which was blank in some records, and a record was deleted, one record's data would become corrupted. Now fixed. - When Displaying Entire Database, or Matching Records, you can now back up, and display the Previous Page. - Still more bug fixes. Version 5.3: 98544 bytes. Released January 1992 - Added hardcopy print-out options. - Added support for mailing labels. Version 5.31: 99448 bytes. Limited Release, April 1992 - A 1000 record version of 5.3, with some bugs fixed. Version 5.32: 98764 bytes. Released May 1992 - A bug in V5.3 would crash the program if the default of 9 fields was accepted, while Creating a New Database. Corrected. - Using the "-f" switch would sometimes cause an "Illegal Function Error". Corrected by requiring an "!" to be placed at the end of the filename. - In an attempt to eliminate extraneous characters, the Input Requester would not allow input of characters > Ascii 126. Without thinking, I was hampering European users. Ascii values of 140-255 are now also accepted. - When using the Print Displayed Record (F8) option, the first line of the database was sometimes being printed 4-6 characters to the left of the requested column. At other times, a blank line was inserted first, before printing the remainder correctly. These problems have been corrected.
