The table below lists all documented opcodes in extension set A7 for IBM mainframe processors. Each opcode links to a text section with some additional info on the pertinent opcode.
Please note that the creation of descriptions for all individual instructions is an ongoing process. As yet no such descriptions have been created for the opcodes on this page.
Entries with a slightly darker background are no longer supported
on current mainframe hardware and/or not supported by IBM's current
of HLASM. The associated mnemonics are printed in italics.
All instructions in this table are four bytes in length. The first byte always has a value of X'A7', the second half of the second byte designates the exact instruction.
Extension sets have no associated mnemonic. These are denoted by their opcode in hexadecimal notation. These link to additional opcode tables.

|Dinos are not dead. They are alive and well and living in data centers all around you. They speak in tongues and work strange magics with computers. Beware the dino! And just in case you're waiting for the final demise of these dino's: remember that dinos ruled the world for 155-million years!|
