PRODUCT : TURBO PASCAL NUMBER : 320
VERSION : 3.01A
OS : PC-DOS
DATE : July 11, 1986 PAGE : 1/1
TITLE : LCD DISPLAY BLOCK HIGHLIGHT PATCH
The IBM Convertible, as well as many other portable LCD displays
do not respond well to the video attributes that Turbo Pascal
uses to emphasize menu items, error messages, and marked blocks
of text. The following patch to the attribute table of Turbo
Pascal makes the display more readable by displaying the
highlighted text in reverse video.
Your Turbo Pascal program file should be installed using TINST.
Select S for screen installation, then 4 for "b/w display mode -
80x25". Answer "N" to the question about screen blink.
In application programs compiled by the patched TURBO.COM file,
in Black and White mode, the procedures NormVideo and LowVideo
will produce normal intensity and reverse video, respectively. On
color systems, these procedures will give Yellow and Grey. On the
monochrome adapter the text will be bright white on grey
background.
Use the DOS utility, DEBUG, to apply the following patch to a
COPY of your .COM file. Copy DEBUG.COM into the directory (or
onto the diskette) where your working copy of .COM is located. At
the DOS prompt, type the following information exactly as it
appears. (Conclude each line by pressing <Enter>.)
Note:
1. DEBUG is not sensitive to upper and lower case. All
addresses are listed in upper case for ease of readability.
2. While in DEBUG, the prompt appears as a dash (-).
3. If you do not receive the appropriate response, press "q",
then <Enter>, to quit. Check your version numbers and, if
correct, try again.
