AUTO [<line number> [,<increment>]]
Extended, Disk
To generate a line number automatically after
every carriaqe return.
ACTO beqins numberinq at <line number> and
increments each subsequent line number by
<increment>. The default for both values is 10.
If <line number> is followed by a comma but
<increment> is not specified, the last increment
specified in an AUTO command is assumed.
If AUTO generates a line number that is already
beinq used, an asterisk is prin t.edafter the
number to warn the user that any input will
replace the existing line. However, typinq a
carriaqe return immediately after the asterisk
will save the line and qenerate the next line
number.
AUTO is terminated by typinq Control-c. The
line in which Control-c is t.ypedis not saved.
Aft.er Control-C is typed, BASIC returns to
command level.
