The table below lists all documented extended mnemonics for instruction BRC (Branch Relative on Condition). Each extended mnemonic links to a text section with some additional info on the pertinent pseudo 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 six bytes in length. The first byte always has a value of X'A7' and the second half of the second byte always has a value of X'4'. The first half of the second byte is the mask to be used for determining whether or not to take the branch. This mask designates the exact pseudo opcode.
Entries with a slightly darker background are not (and never were) supported by IBM's version of HLASM. The associated extended 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! |
