Conditional assembly instructions
Conditional assembly instructions let you determine at conditional assembly time the content of the generated statements and the sequence in which they are generated. Here are the instructions and their functions:
| Conditional Assembly | Operation Done |
|---|---|
| GBLA, GBLB, GBLC,
LCLA, LCLB, LCLC |
Declaration of variable symbols (global-scope and local-scope SET symbols) and setting of default initial values |
| SETA, SETB, SETC | Assignment of values to variable symbols (SET symbols) |
| SETAF, SETCF | External function assignment of values to variable symbols (SET symbols) |
| ACTR | Setting loop counter |
| AGO | Unconditional branch |
| AIF | Conditional branch (based on logical test) |
| ANOP | Pass control to next sequential instruction (no operation) |
Conditional assembly instructions can be used both inside macro definitions and in open code. They are described in How to write conditional assembly instructions.
