Abbr. aU
AUTO prints BASIC program line numbers automatically, which is useful
when you are writing a long program. After you turn on automatic line number
ing, type the first line in your program (using any line number) and press
RETURN. Thereafter, AUTO prints the next line number as soon as you press
RETURN at the end of each line. The increment between the line numbers is
determined by the number you type in the AUTO command.
Parameter: increment number
The increment number can be any positive number that does not exceed 63999,
which is the highest possible line number for a BASIC program. Entering a line
number greater than 63999 creates a syntax error.
Turning Off AUTO
You have to be in immediate mode to use the AUTO command. AUTO prints a
line number every time you press RETURN on a program line containing more
than the line number. Press RETURN on a line containing only the line number
to stop the line numbering. Then issue an AUTO 0 or AUTO with no number to
turn off automatic line numbering.
You can also issue a RUN command instead of AUTO 0 or AUTO, but note
that you must issue one of these commands to turn off automatic line numbering.
Example: AUTO SO
50 INPUT "DATE"; D
70 IITPUT "TIME"; T
Automatically numbers lines in increments of 20.
Type any number for the first line number.
AUTO adds the increment value (20) and prints
the next line number.
