Specifying an Input Data File

To specify that a data file be used for input, use the following OPEN parameters:

For QSAM processing, use INPUT and RDBACK
Note: RDBACK is only valid for tape files. If RDBACK is specified for a non-tape file, the OPEN parameter will default to INPUT.
For BSAM processing, use OUTIN, INPUT, or INOUT.
Note: INOUT cannot be used with AL or AUL tapes.
