purge use from inside program

[John P]

Hello,
I would like to use the 'purge' command inside a program to clear some CAS variables. I can not figure out how to do it. Did anybody found a way to use 'purge' in CAS programs?
Thank you.

Hi, this is a problem I've encountered too. Perhaps, to prevent a variable from being seen in "CAS Vars" it is useful to treat it as a local variable: "LOCAL t", "LOCAL x", etc.

What I am trying to do is to write stand alone prgm. that will delete global variables from inside of the calling program. I do not worry about local vars. because I could define the local variables after calling my stand alone prgm. That would be useful because I would not need to worry that some vars. exist globally that will conflict with vars. I use in the calling program.

Did you try purge(variable)? It works in cas programs for me.
