- ════
- The Screen Grabber Utility is a RAM resident routine that you
- can use to capture CGA, EGA, VGA and text screens displayed by
- other applications and incorporate them into you COBOL programs.
-
- You start the routine by executing the GRAB.COM program. You
- will see a message displayed on the screen that the program was
- loaded. From that time on, any time you want to capture a
- screen that is displayed, you press the SHIFT key and the PRINT
- SCREEN key. When you do this the computer will be held up while
- the contents of the screen are written to a file that will be
- saved on the current drive in the current directory.
-
- The screen will be copied to a file named "SCREEN.xxx". The
- "xxx" portion of the file name is variable. The first screen
- you capture will have a value of "000". The next capture you
- perform will have a value of "001" and so on.
-
- What type of screen mode was captured will determine the size
- and type of file that is captured. A text mode screen will be
- captured to a file 8000 bytes long. A CGA graphic screen
- (320x200) will have a file length of 16000 bytes. An EGA
- graphic screen (320x200) will have a file length of 32000 bytes.
- An EGA graphic screen (640x200) will have a file length of 64000
- bytes. An EGA graphic screen (640x350) will have a file length
- of 112000 bytes.
-
- The screen file that is captured has a number of uses. If a
- text screen was captured you may read it directly with the Egull
- Screen Painter. CGA screens may be display the picture using
- the "CGA_DISPLAY_PIC_FILE" subroutine. EGA screens are
- displayed with the "EGA_DISPLAY_PIC_FILE". You could also use
- the SCRLIB Utility program to copy graphic pictures and up to 99
- others into a single library file.
