UNITCNT

Valid values are 0 through 59. The value 0 means that UNLOAD PLUS does not specify the unit count for the allocation.

If you do not want to use a value for UNITCNT and a value exists in the current default output descriptor, specify UNITCNT 0 in the OUTPUT descriptor statement.

If the OUTPUT statement is for a referenced file and you specify DIRECT NO, specify UNITCNT 0 or 1.

Considerations

The following considerations apply to the UNITCNT option:

• If you specify a UNITCNT integer for tape output, UNLOAD PLUS allocates the number of tape drives that you specified. When a tape volume is at the end of the tape, UNLOAD PLUS begins to write on the next drive immediately so that you do not need to wait for the tape to rewind.
• The value of UNITCNT affects the primary and secondary space allocation requests for SMS-managed data sets when you allow UNLOAD PLUS to optimize primary and secondary extent sizes automatically.

Specifying the default

You can specify the default for the UNITCNT command option in your installation options module by using the UNITCNT installation option. UNLOAD PLUS was shipped with a default value of 0 for this option. The command option overrides the default that is in the installation options module.
