TRS-80 MODEL
III
Postive
numbers are
printed with a
leading blank (instead
of a plus sign); all
numbers are printed
with
a
trailing
blank; and no
blanks
are inserted
before or
after
strings (you can insert them
with quotes as
in line
90)
.
In line
140 no
punctuation is needed; but
in line
190
zero will print
out because
ABC
is
interpreted as a
single variable
which has not been assigned a value
yet.

.

A
trailing semi-colon overrides the cursor-return
so
that the
next PRINT
begins
where the last one left off (see line
300)
.
If no trailing punctuation is used with PRINT, the cursor drops down
to the beginning
of
the
next
line.
