Adding a Dummy Tape Device and Modifying Tape Modes
If you use BIM-EPIC’s tape management, you must define a dummy (non-existent) tape
device. The TSIDASS utility uses this dummy device to satisfy the pre-open checking that is
done by many generalized utility programs, such as SORT.
Do not issue the VSE DVCUP command for this tape device; errors will occur.
Locate the ADD statements in your ASI procedure.
Add a PUB entry for a dummy tape device. For example:
ADD F00,3420T9
Any valid tape device type (and mode) can be specified. The dummy tape device is only
referenced by programs that do pre-open checking to determine device category (tape, disk,
printer, and so on). The actual tape device is selected by BIM-EPIC based on the mode
requested when a program issues an OPEN request.
Write the dummy device address you used on your configuration option worksheet (the
TAPCUU option).
For dual density tape drives, specify the highest available mode setting on the ADD statement
that defines the drive. For example:
ADD 880:884,3420T9,D0 (6250 BPI on a 1600/6250 drive)
