The table below lists all documented opcodes in extension set 01 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 two bytes in length. The first byte always has a value of X'01', the second byte designates the exact instruction. Hence, the instructions on this page take no arguments, unless they be implied.
Entries with a slightly darker background are no longer supported
on current mainframe hardware and/or not supported by IBM's current
version
of HLASM. The associated mnemonics are printed in italics.
Opcodes that have no (known) mnemonic assigned to them are denoted by
their
hexadecimal opcode; these are explained below the table.

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! |
