BASIC
Whenever you PRINT
@
on the bottom line of the Display , there is an automatic
line-feed, causing everything displayed to
move
up one line. To suppress this,
use a
trailing semi-colon
at
the end of the statement.
Example:
100 PRINT®
1000,
1000;
110GOTO110
Use
a
trailing semi-colon or comma any time you want to suppress the line
feed.
PRINT TAB (expression)
Moves the cursor to
the specified
position
on
the current line (modulo
*
1 28 if you
specify TAB
positions
greater than 127). TAB
may be used several times in
a
PRINT
list.
The value
of expression
must be between and
255
inclusive.
Example:
1 PRINTTAB
(5)
"TABBED
5";
TAB(25) "TABBED
25"
No
punctuation is required after
a TAB
modifier.

Numerical expressions may
be used to specify
a
TAB position. This
makes TAB very
useful for graphs of mathematical
functions
,
tables,
etc. TAB cannot be used
to
move the cursor
to
the
left. If cursor is beyond the specified position,
the
TAB
is
ignored.
*Modulo A cyclic
counting system. Modulo 64 means the count
goes from zero to
63 and then starts over
at zero.
Note: In 64 characters/line mode, TAB will
tab (count)
over correctly (eight
characters per tab). In double-size mode
(32
characters/line),
the
TAB
function tabs
over in the following manner: eight characters, two
characters, eight characters,
two
characters,
etc.
