TITLE : FLOATING POINT EVALUATION - PATCH
The following patch solves a problem with dividing floating point
evaluation.
To apply this patch, you will need to use the DOS utility DEBUG.COM.
You may obtain a copy of DEBUG.COM from one of your original PC-DOS
or MS-DOS diskettes.
NOTE: 1. Do not patch your original Turbo C disk, use a working or
backup copy of TCC.EXE and TC.EXE for this patch.
2. DEBUG is not sensitive to upper and lower case. All ad-
dresses are listed in upper case for ease of readibility.
3. XXXX,YYYY,ZZZZ are hexidecimal digits returned by DEBUG.
You must replace these digits accordingly when typing
in your commands.
4. While in DEBUG, the prompt will appear as a dash (-).
5. If you do not receive the appropriate response,press "q"
followed by
version number and, if correct, try again.
6. TCC.EXE and TC.EXE will not fit together onto a 360K disk.
To patch both programs on a floppy disk, you may need to
copy TCC.EXE and DEBUG.COM onto one disk and perform the
patch. Save the patched version of TCC.EXE to another
disk. Repeat the same steps using TC.EXE.
At the DOS prompt, type the following information exactly as it
appears (Conclude each line by pressing

Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!
This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.
But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
