The table below lists all documented opcodes in extension set for IBM mainframe processors. Each opcode links to a text section with some additional info on the pertinent opcode.
Remark:
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.
All instructions in this table are four bytes in length. The first byte always has a value of X'9D', the second byte has a value in the range X'00' through X'0F' and designates the exact instruction.
All entries in this table have a slightly darker background because the entire extension set is no longer supported on either current mainframe hardware or by IBM's current version of HLASM. The associated mnemonics are printed in italics.

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! |
