I have both Borland C++ 5.02 with patch1 and BCB 5 with patch 1 both
installed on my machine. I notice that my path in my autoexec.bat
indicates paths all my borland products (including these two)
Since BCC32.exe and a few other files are on both paths, but
different files, will it choose the correct .exe when I alternate
between these two compilers?
Not reliably, so you better avoid such a mixup.
The best way I've found is to set *none* of the installed compiler
toolchains' environment variables directly in autoexec.bat, because
whatever choice you make there will be wrong for the majority of them
as soon as you have more than two, anyway.
Instead, have a central "batches" directory in the PATH, and a tool
that lets you both add and *remove* entries from the PATH, the tool
itself installed in a directory on the PATH (I use a freeware from the
Simtel.Net DOS collection).
Proceed by writing a pair of batch files in "batches" per toolchain to
"enable" and "disable" it, respectively. These batch files should
prepend the toolchain's entries to the PATH, and remove them again,
respectively, and create/change/remove environment variables, while at
it.
That way, you can type "en_b5.bat" (or use it as the startup batch
file in a desktop link for a "bc++5.02 shell") to have a command line
environment fit for use with C++ 5.02, and "dis_b5.bat" to turn it all
off again. For good measure, change the PROMPT, too, so it's always
obvious which mode of operation the shell is currently in.
This kind of setup may feel like a pain in the lower back at first,
but it more than pays off in the long run, especially if you have
considerably more than two toolchains available (I have roughly 10
altogether). If you find you routinely use one compiler much more
than the others, you can still call up its enabler batch at the end of
autoexec.bat for convenience.
