The EREP Reference applies to EREP Version 3,
Release 5.
The following operating systems can run EREP:
- DOS/VS, DOS/VSE, VSE/ESA ™, and VSE/Advanced Functions—known
collectively in this book as VSE systems.
- VS2, MVS/370, MVS/XA ™, MVS/ESA ™, OS/390 ®, and z/OS ® —known
collectively in this book as MVS ™ systems.
- VM/370, VM/SP ™, VM/SP/HPO, VM/XA, VM/ESA ®, and z/VM ® —known
collectively in this book as VM systems.
If EREP 3.5 is not installed on your system, some of the information
in this book may not apply. You can find out which level of EREP your
system supports by checking the release number of the EREP tape last
installed; the release number is in the System Control Programming
Specifications, which accompany the EREP tape.
Note: New releases of EREP are always downward
compatible. That is, the latest version of EREP always runs on
your system. New releases also include new functions that you can
only use if you have the latest version of your operating system;
but generally, old functions are not eliminated. The same is true
of this book, although some very old versions of EREP (for example,
IFCEREP0) are no longer supported.
