I opened a dcb load library with the same load mod name as the first Did an attach DCB= TASKLIB=
Didn’t pick it up from there as the module from the first load lib with same name was linked REUS > On Feb 5, 2021, at 3:48 PM, Seymour J Metz <sme...@gmu.edu> wrote: > > RENT implies REUS.. > > > -- > Shmuel (Seymour J.)
