LIST
COMMAND: RE NUMbers program lines.
The parameter <old line number> specifies the current existing line number at which
renumbering is to commence. If <old line number> is omitted, renumbering will
commenr.p from the beginning of the program.
The parameter <new line number> specifies the new starting line number for the
renumbered lines. If <new line number> is omitted, the renumbered program will
start at line 1
0.
The parameter <increment> specifies the numeric step between each of the
renumbered lines. If <increment> is omitted, the value ofthe numeric step will be 1
0.
RE NUM takes care of all GO SUB, GOT 0 and other line calls. However, line number
references within string expressions, such as those issued in KEY commands, are not
altered; neither are line refere,nces within REM statements, nor the <line number
expression> in a C H A I N or C H A I N MER G E command.
Line numbers are valid in the range 1 to 6 5 5 3 5.
