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.
PRINT @ position, item list
Specifies exactly where printing is to begin.
The
@ modifiermust be a number
from 0 to 1023. Refer to the Video Display worksheet, Appendix
C,
for the exact
position
of
each location 0-1023:
100 PRINT @ 550, "LOCATION 550"
RUN this to find out where location
550
is.
