{{R to related topic}}
In the [[IBM]] conditional assembly language, the most important statements are:
}}
* MACRO and MEND - used to start and finish a macro
* AIF, AGO, ANOP, AEND, AEXIT and MEXIT - used to control the generation of different assembly language statements, depending on the nature of the macro's supplied arguments.
* SETx - used to manipulate variables within the macro.
=== Alternative use ===
The conditional assembler is not restricted to generating assembler code and was used by IBM in the 1970s onwards to generate [[COBOL]] or [[PL/1]] statements for compiling into [[CICS]] application programs.
