Aki,

The corresponding assembly directives are .if and .endif. You can find information on these in chapter 5 of the Assembly Language Tools user's guide:

Hi Richard,

One more question about this. Customer tried to use .if(1) and found the below error. It seems that the conditional assembly can not be used in this way?

You cannot have .if .else or .endif starting on the first character of a line. You need at least one white-space character before the dot. Put a space or a tab before each one and it should be fine. i.e.

Change:

.if(1)

to:

.if(1)

Regards,

Richard
