Tape File Management Utilities
DETACH Command
Issue the DETACH command only if the DYNVM Extension interface is active.
This command passes a request to DYNVM to detach the indicated tape drive
from the VSE pool and assign it to the VM free tape pool. The format is:
DETACH filename,SYSnnn
Example:
// JOB DETACH SYS010 TAPE
// TLBL FILEA,'DSN'
// EXEC TDYNASN
DETACH FILEA,SYS010
/*
/&
VTSTOP Command
Issue the VTSTOP command if the HOLD option was used when creating a
VTAPE using the Dynam/T automatic VTAPE interface. The VTSTOP command
will release the assignment to the specified logical unit and then issue the
appropriate VTAPE STOP command. The format is:
VTSTOP SYSnnn
Example:
// JOB VTAPE STOP SYS010
// EXEC TDYNASN
VTSTOP SYS010
/*
/&

Cause TDYNASN to indicate 80-byte records when assigning/opening SYSIPT
tapes.
User Labels
User labels required by a program must always precede TDYNASN if any labels
are also required by a TDYNASN function. Otherwise, when encountering label
information after TDYNASN, job control writes over any labels encountered
prior to TDYNASN.
