Extended Mnemonic Macros for IFOX Assembler

Many of the more recent programs written in assembler rely upon extended mnemonic op codes that were not available in the MVS assembler - Assembler H (IFOX00).  Jan Jaeger has written a set of macros that provide the equivalent functionality of these newer opcodes to Assembler H, which will allow a number of programs to correctly assemble that would otherwise be unavailable for use by the Hercules' community.

From the documentation member of file #177 of the CBT tape:

... is from Jan Jaeger, and contains an IEBUPDTE-
unloaded library of macros, which simulate XA, ESA, OS/390,
and z/OS (64-bit) instructions. The intent of this
library is to be able to assemble newer code on an
older version of the Assembler, even perhaps on
IFOX00 ... The original version of this file came from the
(now defunct) FILES section of the Hercules 390 Yahoo group.

Installation

The installation jobstream - $mnemac.tgz [MD5: 31894C187DBCE21CBFC927E805373272] - uses IEBUPDTE to create, load, and catalog a user macro library - SYS1.MNEMAC  Download the archive and extract the jobstream (WinZip on Windows or tar on Linux).  Submit the jobstream - $mnemac.jcl.  The target volume is SMP001 (on a 3350) and may be changed as required for your system.
