Re: IFS data

+++++1!

One thing to be sure of is to declare the return value as an integer type, if not, you get a pointer back, and that will give you incorrect results. Also, IIRC, to declare the variable you pass in for the type of access with *BYVAL. I hope I got that right with my memory far from any code. Scott is the one who reminded me of that sometime in the last 20 years or so!! Many thanks, my friend!

Oh yeah, it's the CALLPRC command.

Using CHKOUT/CHKIN is a bad idea.  What if the file has been checked out already and you check it in?

Use the access() API, it's what it was designed for.

Or one of the half-dozen or so free utilities that are on the Internet. (Which will either use access() or stat() under the covers.)
