Ch professional is a Unix type 'c' shell which has implemented a 'c'
interpreter which is ANSI 'c' compliant.  since the source is ANSI 'c'
complaint, it makes for a tool that runs your 'c' source and can easily be
compiled. This is the vendors claim.

Soft links are a utility that allows you to use a folder as a pointer to a
different folder. A nice utility to use.  Unix folders are set as their
"standard goes", but with soft links you can point the standard folders to
some other named folder, even on a different drive.

example:
One of the folders under the root system in unix is /tmp, but I have my tmp
directory setup on a different drive.

So i execute "ln -s g:/win2k/tmp /tmp".  The /tmp folder remains empty, but
a "ls /tmp" list the files in g:/win2k/tmp.  Makes for convenient directory
organization.
