Macro Assembler
when expanded will include a unique assembler generated label in place of more. For example:
expands to:
if invoked a second time, the label more would expand to ??0002.
4.3.8.21 ALIGN
The ALIGN directive aligns whatever is following, data storage or code etc., to the specified boundary
in the psect in which the directive is found. The boundary is specified by a number following the
directive and it specifies a number of bytes. For example, to align output to a 2 byte (even) address
within a psect, the following could be used.
Note, however, that what follows will only begin on an even absolute address if the psect begins on
an even address. The ALIGN directive can also be used to ensure that a psect’s length is a multiple
of a certain number. For example, if the above ALIGN directive was placed at the end of a psect, the
psect would have a length that was always an even number of bytes long.
4.3.8.22 REPT
The REPT directive temporarily defines an unnamed macro, then expands it a number of times as
determined by its argument. For example:
will expand to
down foobar
??0001 decfsz foobar
ALIGN 2
