- Introduction To Batch (Bat) Files
-
- Batch File commands are the most powerful and
- versatile of the DOS commands. Writing Batch Files
- is the best way to learn how to use the DOS commands.
-
- In the next lessons you will write many Batch Files.
- You'll have an opportunity to see these Batch files
- come alive with the Menus, Programs and color
- combinations. You'll experience a sense of power
- that you have over the computer.
-
- This is a real accomplishment to learn one of
- the most powerful and useful parts of DOS. You'll be
- one of the few persons who'll know how to write a
- Batch File, a Program and a Menu---and in color.
-
- HOW TO WRITE BATCH FILES
-
- BATCH (BAT) FILE
- Bat (short for Batch File) is not a DOS command,
- but a file that is created with the Copy Command. It
- has special powers given to it by DOS. Bat Files can
- instruct the computer (DOS)) to carry out commands.
-
- Batch File commands can make the computer (DOS)
- create Menu-Driven-Programs; automate many DOS
- functions; beep; blink; change colors; show you
- what's in a file; print a file, and perform many other
- functions.
-
- GETTING STARTED
- To do the Lessons from this disk or from the
- Manual, you must first format a disk with the System
- files so it will start your computer.
-
- FORMATTING A DISK
- If you have only one disk drive, type the following
- next to the A> prompt:
- Format A:/S <press the Enter key>
-
- The computer will instruct you on what to do.
-
- If you have two disk drives, insert your DOS disk
- into drive A. Insert a Blank disk into drive B:.
- Now type the following next to the A prompt:
- Format B:/S
-
- When formatting is complete remove both disks.
- Insert your formatted disk (from drive B>)
- into the A> drive.
-
- THE COPY COMMAND
- The most versatile DOS command is the Copy command.
- With the Copy command all sorts of Batch Files can
- be created. The Batch Files being a special DOS file
- can give the computer all sorts of commands
- -3-

-
-
-
-
- from copying a file to formatting a disk.
- In this lesson the interest is in writing Batch Files,
- Programs and Menus. All of which the Batch File
- does very well.
-
- You'll first write a simple Batch File that will tell
- the computer to show you all the files (contents) of the
- directory of the disk in drive A.
-
- Check to see that your formatted disk is in the A> disk drive.
-
- WRITING THE FIRST BATCH FILE
- With your formatted disk in the disk drive, type the following
- next to the A:\> Prompt, like this:
- Copy Con First.Bat
- A:
- Dir
- Press F6 key, <then press Enter key>
- -------------
-
- THE BAT FILE ABOVE TELLS US:
- ▀ That the first line contains the Copy command and
- the name of the Bat file (First).
- ▀ The next word after Copy is "Con" which stands
- for CONsole (keyboard). Con instructs the Copy command
- to copy from the keyboard what you are about to write.
-
- ▀ The second line "A:" stands for the A drive. This tells
- the computer that you are working with the disk in
- the A drive.
- ▀ The third line tells the computer that you wish to see
- on the screen the contents of the directory that is on
- the disk in the A drive.
- ▀ Line four is the Function key F6 (large key on top
- row) that tells the computer (DOS) that you are
- finished writing the Batch File.
- All that is left now is to strike the Enter key.
- The Batch file will be saved on the disk in the A> drive.
-
- Now you will write four Batch files that will be used
- to change the screen color (Background) to Blue or Red and
- the letters to White or Yellow. You'll then display the
- files in the A: directory.
-
- WRITING THE FIRST COLOR BATCH-FILE (BB.Bat)
- (BB.Bat.. Blue Screen...also called Background)
- Type the following next to the A:\> Prompt, like
- sa this:
- Copy Con BB.Bat
- BB.Bat
- Dir
- Press F6 key, then press Enter key.
- -------------
-
- WRITING THE SECOND COLOR BATCH-FILE (W.Bat)
- (W.Bat..White letters... also called Foreground)
-
-
- -4-
-
-
-
-
-
-
- Type the following next to the A> Prompt, like this:
-
- Copy Con W.Bat
- W.Bat
- Dir
- Press F6 key, then press Enter key.
- -------------
-
- WRITING THE THIRD COLOR BATCH-FILE (Y.Bat)
- (Y.Bat.. Yellow letters)
- Type the following next to the A> Prompt. like this:
-
- Copy Con Y.Bat
- Y.Bat
- Dir
- Press F6 key, then press Enter key.
- -------------
-
- WRITING THE FOURTH COLOR BATCH-FILE (RB.Bat)
- (RB.Bat.. Red background)
-
- Copy Con RB.Bat
- RB.Bat
- Dir
- Press F6 key, then press Enter key.
- -------------
-
- We'll now go to Chapter 2 and see the Color Codes
- for the 8 foreground and 8 background colors.
-
- (8 X 8 =64 possible color combinations)
