TAB
Function
Syntax
n
Remarks
Example
Tabs the cursor or the print head to a specified
position, in PRINT, LPRINT, or PRINT#
statements.
TAB(n)
is an integer expression in the range 1 to 255.
If the current cursor or print position is
already beyond the specified value "n" TAB
goes to that position on the next line. Space 1
is the leftmost position, and the rightmost
position is the defined width.
If the value of "n" exceeds the defined width,
the modulo operation is applied. For example,
PRINT TAB(243) on a 40-column screen is the
same as PRINT TAB(3), because 243 MOD
40+3.
A semicolon is assumed to follow the TAB
function; thus GWBASIC does not add a
carriage return if the TAB function is at the
end of the list of data items.
