A '''Conditional Assembly Language''' is that part of an [[Assembly Language]] used to write [[Macro (computer science)|macros]].

== Example ==

In the [[IBM]] conditional assembly language, the most important statements are:-

Line 7 ⟶ 8:

* 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 in fact used by IBM in the 1970's1970s onwards to generate [[COBOL]] or [[PL/1]] statements for compiling into [[CICS]] application programs.
