- TITLE : PATCH FOR ^KW BLOCK WRITE DISK FILE SIZE NOT
- TRUNCATED BUG
-
-
-
-
- This handout describes the patch needed in order for the Turbo
- Pascal 4.0 editor to correctly block copy a portion of code out
- of a source file and truncate the file's size on disk. The
- following patch should be made to the TURBO.EXE file using the
- DOS utility, DEBUG.
-
- 1. Copy TURBO.EXE to a file called TURBO.TXT. (DEBUG will
- not allow modifications to be made to an .EXE file.)
-
- 2. Load TURBO.TXT into DEBUG with the command:
-
- DEBUG TURBO.TXT
-
- 3. At DEBUG'S "-" prompt, enter the command E CS:3FCD. Press
- <Return>. This allows you to edit the code at address
- CS:3FCD. The number 01. will appear. Type 3 next to it
- and press <Return>. Enter W <Return> to write the patched
- program to disk and Q <Return> to quit. You have
- successsfully patched Turbo Pascal. Your DEBUG session
- should look something like this:
-
- C:\TURBO>debug turbo.txt
- -e CS:3FCD
- 29C9:3FCD 01.3
- -w
- Writing 1C248 bytes
- -q
-
- 4. Rename TURBO.TXT to TU.EXE. (Use a name other than
- TURBO.EXE so you can distinguish between the original and
- corrected versions.)
