p1,m1

These variables specify the binary field in the input record to be compared to the bit constant.
  • p1 specifies the first byte of the binary input field to be compared to the bit constant, relative to the beginning of the input record.1 The first data byte of a fixed-length record (FLR) has relative position 1. The first data byte of a variable-length (VLR) record has relative position 5 (because the first 4 bytes contain the record descriptor word). All fields to be tested must start on a byte boundary and must not extend beyond byte 32752.
  • m1 specifies the length of the field to be tested. The length can be 1 to 256 bytes.

1 If your E15 user exit routine formats the record, p1 must refer to the record as reformatted by the exit.
