Welcome to my home page. I intend to add more information as time goes on, but right now this is what I have.

The following link --> OPCODES 2.04 <-- can be used to download the OPCODES 2.04 package. This package provides a MACLIB for use under the CMS operating system which provides macros that allow newer instructions to be used on older assemblers which do not support those instructions. In particular, it was designed to augment the capabilities of Assembler XF (the ASSEMBLE command), which ships with z/VM. However, it is also useful with newer assemblers. This download file is in VMARC format. Transfer this file to a CMS system in binary, using fixed-length, 80-byte records, then use VMARC to unpack the archive. If you don't have VMARC already, see the VM download page. (The OPCODES package linked on this page is public domain by me. For licensing terms for the downloads available on the VM download page, see that page.) Here's another useful link for those running z/VM: Track for z/VM.
