TITLE : STRUCTURE PUSH FLOATING POINT PATCH
______________________________________________________________________________
The following patch solves a problem with pushing structures
with floating point elements onto the stack in Turbo C.
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 <Enter>, to exit from DEBUG. Check your
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 <Enter>).
