.fclist/.fcnolist
Control the Listing of False Conditional Blocks
4-46
Syntax
.fclist
.fcnolist
Description Two directives enable you to control the listing of false conditional blocks.
The .fclist directive allows the listing of false conditional blocks (conditional
blocks that do not produce code).
The .fcnolist directive suppresses the listing of false conditional blocks until
a .fclist directive is encountered. With .fcnolist, only code in conditional blocks
that are actually assembled appears in the listing. The .if, .elseif, .else, and
.endif directives do not appear.
By default, all conditional blocks are listed; the assembler acts as if the .fclist
directive had been used.
Example This example shows the assembly language and listing files for code with and
without the conditional blocks listed:
Source File:
AAA .set 1
BBB .set 0
.fclist
.if AAA
ADD #1024, A
.else
ADD #1024*10, A
.endif
.fcnolist
.if AAA
ADD #1024, A

ADD #1024*10, A
