Alternative mnemonics for some branch relative instructions
For some branch relative statements, there are alternative mnemonics. These are:
| Instruction | Alternative | Description |
|---|---|---|
| BRAS | JAS | Branch Relative and Save |
| BRASL | JASL | Branch Relative and Save Long |
| BRCT | JCT | Branch Relative on Count |
| BRCTG | JCTG | Branch Relative on Count |

Extended mnemonics are also provided for some machine instructions that are not branches. These extended mnemonics can be used to represent alternative names for the same instruction or for easy reference to useful cases where particular values are used for masks or immediate values in the base instruction. All extended mnemonics are documented with their corresponding base instructions in z/Architecture® Principles of Operation (SA22-7832).
