I have Microsoft's Visual C++ 6.0 installed on my computer.
My computer uses Windows XP Professional service pack 2.

I have a copy of Borlands C++5 installation disk (and associated manual) but I haven't installed it. This is because
someone once told me that two C++ compilers couldn't be
installed on the same hard drive. ( I think that that person said that the reason for this was because the CPU wouldn't
really know which compiler to go to.)

Probably, a way around this is to partition my hard drive with
something like Partition Magic, or similar type software. But
I believe this is prone to 'crashes' - not because of the
software, but because I'm not really computer literate. I would probably do something wrong and crash the computer.

Is there a way that I can install Borland's compiler on the same hard drive that I have already installed Microsoft's
compiler?

Another source has told me that it is only a matter of making the
'appropriate call to the compiler'. But my abilities are limited to
basic programs. Some aid along these lines would be appreciated.
