Assembler Directives and Pseudo-Operations

.ALIGN Directive

The .ALIGN directive advances the current location counter to the next

speciﬁed “boundary.”

Syntax

.ALIGN [ boundary]

Parameters

boundary An integer value for the byte boundary to which you

want to advance the location counter. The Assembler

advances the location counter to that boundary.

Permissible values must be a power of 2 and can range

from one to 4096. The default value is 8 (double word

aligned).

Example

This sample program adds a 21 bit ﬁeld to the data pointer. Then a

branch is taken to the label “page” that has been page-aligned.
