CTSTAPER is used to test the tape management system by issuing OPEN, CLOSE, READ, WRITE and FEOV (force end-of-volume) macros to exercise the tape functions. Up to 10 tape drives may be used per step, with control information provided in the ddname and EXEC parameter.
This utility produces the CA TLMS Tape Activity Report, and messages may be sent to the system console from an optional SYSIN data set.
The parameter value is optional and may be the value JFCB or ABEND. If omitted, the report will print each OPEN and CLOSE for a DD statement. If JFCB is specified, a hexadecimal dump of the JFCB is also printed with each OPEN and CLOSE. If ABEND is specified, CTSTAPER will terminate with an S0C3 abend after tape processing instead of a normal CLOSE. This allows testing of third disposition processing.
Processing for each tape is specified by ddname in the following format:
ttnnxxxx
Where:
Is one of the following:
read input
write output
The number of volumes to process
User name for DD
CTSTAPER writes 24 characters twice per data set per volume, and expects to read the same data. It uses FEOV to create multivolume data sets without writing more data.
CTSTAPER can display text to the system console and also allows the job to be aborted. If the SYSIN DD statement is present, the first 70 characters of each record will be issued to the console as a WTO before any tape processing is started; a WTOR is issued at EOF, which causes a pause in the job stream. This pause allows the operator to read the text before processing is started. Additional pauses may be caused by placing *PAUSE* in positions 1-7 of a record. The WTOR issued at any pause prompts the operator for a reply of U or C; C (cancel) causes an S122 abend, and any other reply allows processing to continue.
The SYSIN data set provides the means to request detail setup and allows the operator to abort, if required.
