The SOPADGN option specifies the action to be taken in BetterGener applications if the LRECL defined in the JCL for SYSUT2 is larger than the SYSUT1 LRECL or the internally processed record length when the SYSUT1 LRECL is modified by features.
RC0
The delivered default specifies that BetterGener should issue a WER462I, pad fixed-length output records with binary zeros, and issue a return code of zero.
RC4
Specifies that BetterGener should issue a WER462I and pad fixed-length output records with binary zeros. A return code of 4 will be issued if not overridden by a higher return code set for another reason.
IEB
Specifies that BetterGener should transfer control to IEBGENER when the SYSUT2 LRECL is larger than the SYSUT1 LRECL.
