.elifdef — Assemble If Alternative Symbol Defined
Syntax
.elifdef
symbol
Description
symbol
Specifies a user-defined symbol
The
.elifdef
directive is used in a conditional assembly block. It is equivalent to
the
.else
directive followed by an
.ifdef–.endif
block (see
.ifdef
and
.endif
directives). Its use obviates the need for multiple
.endif
directives in conditional
blocks that have multiple alternatives.
The
.elifdef
directive is optional within a conditional assembly block.
Example
.ifdef option1
moveq #1,d0
.elifdef option2
moveq #2,d0
.elifdef option3
moveq #3,d0
.endif
