Thanks. And one more question.

[James Choi]

Thanks to all of you who replied to my questions.  Here is the summary of
the answers I got.

DOS partition larger than 32M is allowed as long as I do not care to read
it under Unix.

Every message I got recommened SCO C++ for SCO environments.  Some of the
replies came from SCO people so it could be biased.  But there was no reply
from any other makers.

No C++ recommendation was made for ISC environment.  My question about
Oregon C++ was lost in the void.  (one person wrote me stating he liked
Oregon Pascal.)

I have one more question.  You can save my neck by informing me of the
solution.  How do I access PC hardware ports under Unix?  Microsoft C or
Borland C has outport or something similar to access it.  I could not find
anything equivalent even after searching ISC C (New C) manual from cover to
cover.  I would be of great help if someone can tell me what the function
name is, or how it is handled in Unix.

thank you in advance.  I will summmarize the answers if anyone is
interested.
