The table below lists all documented extended mnemonics for instructions:

Opcode Mnemonic Description Table Type
EC70 CGIT Compare Grande Immediate and Trap Extended Mnemonics
EC71 CLGIT Compare Logical Grande Immediate and Trap Extended Mnemonics
EC72 CIT Compare Immediate and Trap Extended Mnemonics
EC73 CLFIT Compare Logical Fullword Immediate and Trap Extended Mnemonics
EC76 CRJ Compare Register and Jump Extended Mnemonics
EC77 CLRJ Compare Logical Register and Jump Extended Mnemonics
EC7C CGIJ Compare Grande Immediate and Jump Extended Mnemonics
EC7D CLGIJ Compare Logical Grande Immediate and Jump Extended Mnemonics
EC7E CIJ Compare Immediate and Jump Extended Mnemonics
EC7F CLIJ Compare Logical Immediate and Jump Extended Mnemonics

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

Opcode Assignments.

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.

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'70' thru X'7F'. 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!
