Although it would be nice if QSAM had equivalents to equivalents to NOTE and POINT. In TSS, you use SETL to point to a logical VPAM record. Check the references I gave you. -- Shmuel (Seymour J.)

This opens serialization hazards which ISPF Edid covers with ENQ EXC SPFEDIT. Of course the programmer can code this explicitly, but it should be in the access method. ISPF LMPUT allows multiple concurrent PDSE member creation. If multiple tasks attempt to create the same member name, the last STOW (LMCLOSE) one wins. Only within a single job because LMPUT requires ENQ EXC SYSDSN, needlessly because PDSE does its own serialization With PDS, data may be corrupted. >You can use any macro appropriate for the type of member.
