High Level Assembler - Opcodes overview, Extension Sets EC7x

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

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.
