The DT pseudo-op
allows
ASCII text
to be put into memory. The desired
text
IIlJst be enclosed by single
quotes.
For example,
TEST:
DT' ABCDEF'
DTH
Define text
tenninated
high
The DTHpseudo-op
is like DT, only the last
character
is ORedwith 80H before
it
is written
out.
In the above example, the last
byte ~uld
be C6 hex.
The DTZ pseudo-op
is like DT also,
only it causes a byte of ~~ to be appended
to the text
string.
Thus the example ~uld
be 41 42 43 44 45 46
13~.
The DS pseudo-op
causes
the
assembler
to skip
over
the
number of bytes
specified
by the operand.
Since the object
file
is
scatter
loaded,
the
area
skipped over will
remain undisturbed.
The FILL pseudo-op
is
similar
to OS, only it
fills
the area with a constant,
rather
that
skipping over it.
The constant
to fill
with is specified
with
the
second operand.
