The PURGE directive deletes the definition of a specified macro entry, letting you reuse space.

Syntax

PURGE Macro-Name[,...]

Remarks

It is not necessary to purge a macro before redefining it. You may use PURGE to recover memory during assembly by deleting the contents of unreferenced macros. An Out of Memory condition can occur if a large, general-purpose macro library is included.

Example

The directive:

PURGE   MACRONAME

performs the same function as redefining the macro with no contents, as in:

MACRONAME MACRO
          ENDM

In the following example, assume that MAC1 is a macro included in MACRO.LIB:

INCLUDE   MACRO.LIB
PURGE     MAC1
MAC1      ; Calls the purged macro
          ; but produces nothing
