I have not tried this since 2009 but if the user is able to access Unix System Services and the environment is _BPX_SHAREAS=YES, then you could dynamically increase the TSO region size by increasing rlimit_as (address space size). Sample REXX code at http://billlalonde.tripod.com/rexx/setrlim.txt could be used to do this. http://billlalonde.tripod.com/rexx/getrlim.txt shows the current values. The maximum allowable value for address space size (Unix System Services) can be set in the user OMVS profile (or is taken from an installation default value).

You might be able to increase your REGION size if you logoff and then change it on the TSO logon panel where you put in your password.
