GENERAL: Commenting Out Macro Definitions

Information in this article applies to:

• A51 All Versions
• A166 All Versions
• A251 All Versions

SYMPTOMS

When I write a couple of macro definitions with the second commented out, like this:

%DEFINE (RANGE3)   (16K)         ; Set CS3# Range
; %DEFINE (RANGE3)   (1024K)         ; Set CS3# Range

the second definition is accepted as valid, even if commented out. Is this the correct behavior?

CAUSE

In order to comment out a MACRO definition you must use a Macro comment rather than an assembler comment.

RESOLUTION

The Macro comment has the form

%'

So, in order to comment out a macro definition, place the Macro comment at the start of the definition:

%' %DEFINE (RANGE3)   (1024K)         ; Set CS3# Range

The comment may be terminated either by the end-of-line character or another apostrophe.
