effect ofthese direciives is to
omit
from
the objeci
prc-

code conesponding to the lines
between lines 100
and 200. Memory correspondirg
io the6e lines is skipped

The
effect ofthese directives is to omit error m€ss3ges
fo.
the assembled
program
lines between lines 1oo

The
effect ofihese directives is to suppr€ss,
between
lines
100 and 200, the 4line pag€ spacing
that is
normally
inserted after every 56 lines
ofthe
listed
form
of the assembled
prcgran.
More than one
option may appear on a line. Opiions

we
explain these directives together because
they are
intended
to be used
iogether to
provide
easily read information about ihe
assembled
program.
These
directives ale most useful when the assembled
program
is listed
on
ihe
TITLE and PAGE
allow
you
to divid€
your program
listing into s€gments ihat
bear m€ssages wriiten for your
own conv€nience, much as
you
might add short
explanatory notes to sny complex material.
The PAGi directive caus€s the pdnter to put
out six blank lin€s
(printers
so
equipped will execute a TOP oF IORM), followed
by the messages
you
have
given
for TITLE and PAGE. This causes
the messages to stand out somewhat
from the rest ofthe assembled program
listing.
Usually there is only one TITLE
directive,
giving
the
program
nam€ and date,
and diferent PAGE directives for giving
different
page
messag€s. Then on
listing the
assembled
prcgram,
the same TITI,E
message on every
page
would
be followed
by a differcnt PAGE message.
The blank lin€s that
the PAGE directive
produces
on the 4o-column ATARI

P nter can be
used to break up a long
program
into segments
that can be
mounted in a notebook.
