Hi,

Can someone tell me how I can GETMAIN an area in common storage which
will not be FREEMAIN-ed by OS/390 when the job/STC ends or terminates ?
I want to use this area as a user CVT.

Thanks in advance to those who have taken the effort to reply .

Use a CSA (or ECSA) sub-pool, such as SP241.  Example:

   GETMAIN R,LV=4096,SP=241

If you're running on MVS/ESA 4.2.2 or above (you probably are), use a
name/token pair instead of CVTUSER; it'll reduce the risks of conficts in
the long run, and will also teach you something useful.
