 The SAVEPROF utility performs a TBSAVE on the profile table for the profile
 variable pool currently open.  This can be valuable, in that ISPF never saves
 the profile pool ISPF table until ISPF is exited.  Consequently, if you update
 a variable in ISPF and then time-out of TSO, you will loose that update.
 SAVEPROF ensures that the update will "stick" even if you do "time-out".
