A table of all 2678 instructions currently supported by HLASM has now been added as a new appendix to the HLASM Programmer's Guide (both in the HTML form and PDF). It includes information about operand syntax, base instructions for extended mnemonics, the ranges of OPTABLEs to which that instruction applies, the instruction format, the hexadecimal opcode and the descriptive name of the instruction.
https://www.ibm.com/docs/en/hla-and-tf/1.6?topic=guide-index-supported-instructions This took longer than expected because we had problems fitting the information into the PDF version of the table without getting operands or instruction names split within words. However, our helpful writer has managed to fix most of the layout problems and has added zero-width spaces so that operand splits should only occur between operands. This table is generated by a program from the HLASM instruction tables, where most of the descriptive instruction names are derived from appendix B.2 of the z/Architecture Principles of Operation. We therefore hope it should be practical to continue to maintain it to include any future new instructions. Jonathan Scott, HLASM IBM Hursley, UK
