RE: IFS commands

Actually, the reason you can't (reliably) use access() from a CL program
is that CL cannot pass parameters by VALUE.  The second parameter to
access() is an integer passed by value, but since CL can only pass parms
by reference the API ends up getting a pointer instead of a value.

To the original poster:  This topic has been discussed many times before.
Please search the archives and/or web before asking a question.  Thanks!
