I have for some years had a comprehensive list of all opcodes supported by HLASM showing the range of OPTABLEs for which each one is valid, the instruction format, whether it is an extended mnemonic, the instruction name and some other information. This information is generated systematically by a tool from the HLASM OPTABLE definitions.
I will try to get it added as a new appendix to the HLASM Programmer's Guide, if that is considered practical and maintainable. Jonathan Scott, HLASM IBM Hursley, UK
