This was posted on Hercules email group today by Jay Maynard, and I thought I’d pass it on for those interested in using it to extend older assemblers to include many of the z/Architecture instructions which the z390 already supports:. 

Stephen Powell's macro library for z/Architecture instructions for use with z/VM ASMFX and other older assemblers:

With these macro extensions you may be able to use MVS 3.8 IFX00, z/VM Assembler XF, ASMG etc. to run z390 Mainframe Assembler Coding Contest solutions that depend on some of the newer instructions for 64 bit GPR’s, 16 64 bit FPR’s, extended translate instructions such as TROT, etc.  I don’t see the decimal floating point instructions yet but perhaps they are coming too.
