The table below lists all documented extended mnemonics for instructions:

Each extended mnemonic links to a text section with some additional info on the pertinent pseudo 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.

Extended Mnemonics for instructions in extension set EC

All instructions in this table are six bytes in length. The first byte always has a value of X'EC'. 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 sixth 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 fifth byte.

    Tyrannosaurus Rex 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!
