9.41.3 Instruction syntax ¶

The assembler syntax closely follows the syntax outlined in Enterprise Systems Architecture/390 Principles of Operation (SA22-7201) and the z/Architecture Principles of Operation (SA22-7832).

Each instruction has two major parts, the instruction mnemonic and the instruction operands. The instruction format varies.

• Register naming
• Instruction Mnemonics
• Instruction Operands
• Instruction Formats
• Instruction Aliases
• Instruction Operand Modifier
• Instruction Marker
• Literal Pool Entries
