Format 1
Format 1 specifies the number of bytes for fixed-length records.
- integer-3
- Must be an unsigned integer that specifies the number of bytes contained in each record in the
file.
The RECORD CONTAINS 0 CHARACTERS clause can be specified for input QSAM files containing fixed-length records; the record size is determined at run time from the DD statement parameters or the data set label. If, at run time, the actual record is beyond the 01 record description, then only the 01 record length is available. If the actual record is shorter, then only the actual record length can be referred to. Otherwise, uninitialized data or an addressing exception can be produced.
Usage note: If the RECORD CONTAINS 0 clause is specified, then the SAME AREA, SAME RECORD AREA, or APPLY WRITE-ONLY clauses cannot be specified.
Do not specify the RECORD CONTAINS 0 clause for an SD entry.
