The table below lists all documented extended mnemonics for instructions:
| Opcode | Mnemonic | Description | Table Type |
|---|---|---|---|
| B960 | CGRT | Compare Grande Register and Trap | Extended Mnemonics |
| B961 | CLGRT | Compare Logical Grande Register and Trap | Extended Mnemonics |
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 four bytes in length. The first byte always has a value of X'B9'. The second byte of the opcode designates the exact instruction and has a value in the range X'60' thru X'6F'. This byte is the second byte of the instruction; its second digit is the first nibble in the table below.
The second nibble in the table indicates the mask value for the condition code for the pertinent instructions. In the assembled instructions this is the first half of the third byte.
