Stephen Powell's Macro Library

Stephen Powell created an extensive library of macros to extend the functionality of Assembler XF running under z/VM.  He has made his library available for use by others who wish to assemble programs written for later architectures, but are limited to the public domain assemblers.

The macros are distributed free of charge, free of service, free of support, and free of liability.  Use at your own risk.  They come with ABSOLUTELY NO WARRANTY, including the implied warranties of merchantability and suitableness for a particular purpose, etc.  You may do anything with them that you want, including addition, modification, deletion, redistribution, and incorporation into a derivative work.  You may not, however, restrict what anyone else can do with them in any way.  In other words, this is public domain material.

The library contains the following 610 macros:

Installation

I have packaged the files in two archives - opcodes.tgz [MD5: 89D0C0317914339EF25D53B1B3483D87] and opcodes.zip [MD5: E046FA2D945FFCCF79145B3E821A082C].  The contents of the two archives are functionally identical, however opcodes.tgz was created using tar+gzip and the text files contained therein are in Linux format (lines terminated by x'0a'), while opcodes.zip was created using WinZip and the text files contained therein are in Windows format (lines terminated by x'0d'x'0a').

The files contained in the archives are:

• opcodes1.bin - [EBCDIC] IEBUPDTE jobstream to create a PDS under MVS.
• opcodes1.txt - [ASCII] same content as opcodes1.bin
• opcodes2.bin - [EBCDIC] CMS MACLIB in packed format
• opcodes3.bin - [EBCDIC] documentation, installation instructions, etc.
• opcodes3.txt - [ASCII] same content as opcodes3.bin
• opcodes4.bin - [EBCDIC] assembler source for installation verification program
• opcodes4.txt - [ASCII] same content as opcodes4.bin

Download the archive appropriate to your Hercules' host system, extract the contents, and read/follow the instructions in opcodes3.txt.

Note for VM users:  opcodes2.bin is a CMS MACLIB in a packed format.  Transfer it to a CMS system as a fixed-length file with a record length of 1024 and a block size of 1024.  Then use COPYFILE with the UNPACK option to convert it back to a MACLIB.  For example:

COPYFILE OPCODES2 BIN A OPCODES MACLIB A ( UNPACK

Even though a MACLIB has fixed-length records, I packed it to avoid problems with the internal end-of-file indicators which separate members from causing problems when using OS copy methods, such as are used by MOVEFILE.  Note that this MACLIB is in the newer LIBPDS format, rather than the older DMSLIB format.  Very old versions of CMS may not understand this MACLIB format.  In that case, I suggest they get the MVS job stream (opcodes1.bin) and write an EXEC to separate the members and build their own MACLIB in DMSLIB format.

I hope that you have found my instructions useful.  If you have questions that I can answer to help expand upon my explanations and examples shown here, please don't hesitate to send them to me:
