Eligible compilers
IBM® Automatic Binary Optimizer for z/OS®, V2.1, can optimize CSECTs within program modules that were
generated by the following COBOL compilers:
- Enterprise COBOL for z/OS V4
- Enterprise COBOL for z/OS V3
- COBOL for OS/390® & VM V2
- COBOL for MVS™ & VM V1.2
- COBOL/370 V1.1
- VS COBOL II V1.4.0 (LE enabled modules only)
- VS COBOL II V1.3.x (LE enabled modules only)
Note: COBOL modules that have been processed by CA-Optimizer
cannot be optimized by ABO. For these types of modules it is recommended
to use ABO to optimize the original module created by the COBOL compiler
before it was processed by CA-Optimizer.
