Important Notice
The pages on this site contain documentation for very old MS-DOS software,
purely for historical purposes.
If you're looking for up-to-date documentation, particularly for programming,
you should not rely on the information found here, as it will be woefully
out of date.

Syntax: ALIGN [number]
EVEN
See also: ORG, SEGMENT, STRUCT, Data Declaration Directives
Description:
ALIGN aligns the next variable or instruction on an offset address
that is a multiple of <expression>. The <number> parameter must be
a power of 2 (1,2,4,8,...) less than or equal to the alignment of
the current segment. If <number> is omitted, the alignment is
determined by the align field of the preceding SEGMENT directive.
In a segment containing no instructions, the assembler pads each
skipped byte with nulls (00h). In a code segment, the assembler
inserts a no-operation sequence (not necessarily NOP instructions)
to fill the gap.
This directive is useful for optimizing data and instruction
fetches on processors with 16- or 32-bit data paths.
EVEN is a synonym for ALIGN 2.
