PRODUCT : Pascal NUMBER : 113
VERSION : All
OS : DOS
DATE : September 30, 1994 PAGE : 1/2
TITLE : INTERRUPT 3 PATCH
Turbo Pascal redefines the interrupt 3 vector to its own
interrupt service routine used for handling Ctrl-C. However, the
vector is permanently initialized to that interrupt routine even
though the "U-" directive is specified.
This patch will permanently keep the Ctrl-C vector from being
initialized, but will allow the use of DEBUG break points.
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
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.
