The BASIC Languag
one disk drive connected to your computer and you are using a device other than
unit 8 in the RENAME procedure. You must precede the unit number with U,
and the unit number must be between 8 and 11. You can type ON before U, but
ON is not required.
Note: The drive and unit number parameters and the file names can be
specified with a variable or expression in parentheses.
Examples: RENAME Dl, "OLD" TO "NEW"
Changes the name of file OLD to
NEW.
RENAME "TESTSORT" TO "S0RT1" Changes file TESTSORT to
SORT1.
RENUMBER Abbr. renU
RENUMBER new start line number, increment, old start line number
Renumbers lines in the current BASIC program. This command can be
executed in immediate mode only; you cannot include it in a program.
Parameter
Values
Default
New first line number
Increment between lines
First line number to be
renumbered
Any legal number*
Any legal number*
Any line number in the
program
10
10
First line in the
program
♦Renumbering must not force line numbers to exceed the highest line number allowed, which is
63999, or strange results will occur.
1. Regardless of what numbering scheme is used in the current program, you
can choose any new first line number. If you omit this parameter and thereby use
the default, you must type a comma in place of the parameter in the command.
2. The increment tells the computer how many numbers to skip between line
numbers. Even if the current line numbers are erratically spaced (e.g., 10, 15,18,
20, 30, etc.), the RENUMBER command changes all line numbers so they are
evenly spaced (e.g., 10, 20, 30, 40, 50, etc.). If you omit this parameter, type a
comma in its place.
3. You can give any number in the program as the first line to be renumbered.
This parameter lets you choose a line other than the first one in the program to
begin renumbering.
Examples: RENUMBER 100
Makes 100 the new first line
number. The defaults for incre
ment and first line number to be
renumbered are accepted.
