Please let me know how to mount a tape and how to verify whether it is
mounted or not.
Jerry, in all the replies, some of them sort of testy, no one has
actually responded to you, so let me try. You did ask a very broad
question with no details so I can't be very specific. This does sound
like a homework question or an interview question. I assume your
environment is the IBM z/OS operating system (or one of its predecessors).
In a batch job, you include a DD statement calling for a tape. The
details depend on your installation but as a general example
//ddname DD DSN=MY.TAPE.DATASET,UNIT=TAPE,DISP=(,CATLG)
will mount a scratch (output) tape.
When your program issues an OPEN, OPEN will verify that the tape is
mounted and ready.
If you are writing in assembler, you can use dynamic allocation (SVC 99)
to dynamically mount and input or output tape. DYNALLOC will verify
that the tape is mounted before it returns to you.
