John Putting flesh on Ted's bare bone, here is a sample way to define TSO in the VTAM of the last - as Ted mentioned - decade and more:
VBUILD TYPE=APPL xxTSO APPL ACBNAME=TSO, interpreted and uninterpreted name * AUTH=(TSO,PASS), TSO + PASS * EAS=1, generally one session at a time * FASTPASS=YES, efficient PASS logic * REGISTER=CDSERVR register LU with CD server xxTSO??? APPL ACBNAME=TSO0???, interpreted and uninterpreted name * AUTH=(TSO,NVPACE), TSO + prevent outbound pacing * EAS=1, one session * LOSTERM=SECOND, end session on second VARY INACT * MAXPVT=0, no limit on PIUs pending RECEIVE * MODSRCH=FIRST, required model search option for TSO * REGISTER=NO, do not register LU * VPACING=0 prevent inbound pacing In addition to showing how to define the TSO-user-supporting sessions by means of a model APPL statement, I believe all relevant operands for TSO applications are shown with generally suitable values. An exception to "generally" is MODSRCH=FIRST which is absolutely required - yes, I have a scar to remind me!. Indeed it's a shame that the VTAM developers weren't clever enough to make it the default when a model APPL statement is used and AUTH=TSO is specified.
