You can use the VDELETE or VRESET service to remove variables only
from the function pool. However, if you wish to do some housekeeping
in the other variable pools, you can use the VERASE service. The VERASE
service allows you to remove variable names and values from the shared
pool, the profile pool, or both. You can specify on the VERASE service
request a list of one or more variable names to be removed from the
shared pools or both. For example:
ISPEXEC VERASE (AGE ADDRESS SOCSEC) PROFILE
might
be used to remove variable values for age, address, and social security
number from the profile pool.
For detailed information about VERASE and other services, refer
to the z/OS V2R2 ISPF Services Guide.
