Vector Basic Interpreter Basic 80, Reference Manual, Page: 99 / 190

Purpose:
Remarks:
RENUM [[<new number>] [,[<old number>] [,<increment>]]]
Extended, Disk
To renumber program lines.
<new number> is the first line number to be used
in
the new sequence. The default is 10. <old
number> is the line in the current program where
renumbering is to begin. The default is the
first line of the program. <increment> is the
increment to be used in the new sequence. The
default is 10.
RENCH also changes all line number references
following GOTO, GOSUB, THEN, ON •••GOTO,
ON •••GOSUB and ERL statements to reflect the new
line numbers. If a nonexistent line number
appears after one of these statements, the error
message "Undefined line xxxxx in yyyyy" is
printed. The incorrect line number reference
(xxxxx) is not changed by RENUM, but line number
yyyyy may be .changed.
RENUM cannot be used to change the order of
program lines (for example, RENUM
15,30
when the
program has three lines numbered
10, 20
and
30)
or to create line numbers greater than
65529.
An "Illegal function call" error will result.
Renumbers the entire program.
The first new line number
will be 10. Lines will
increment by 10.
RENUM
30G,,50
Renumbers the entire pro-
gram. The first new line
number will be
300.
Lines
will increment by 50.
RENUM
1000,900,20
Renumbers the lines from
900
up so they start with
line number
1000
and
increment by 20.
