- 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
- addresses 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>).}
