and Add. You can
specify
thetine number of the first numbered line and the stepsize, thalis,
the difference between each line numberand the next.
Choosing Rensse, An In,orAdd willrationalisethelinenumbersinyourpmgram Add will numberall thelines in theprograns; An In will numberonly those lines which already have numbers, and Rennse will number only those lines which arereferencedhy GOTO, GOSUt or other BASIC 2 Plus commands. In all tlsree cases
the numbering will start
at the number specifiedby First 1 ine,and willcontiuue in steps specifiedby Line Nu Step.
Rationalising line numbers means more than just renumbering the lines; it also means that
references solines throughout theprogram are kept consistent. Forenample, iftheprogram
contains theline
GOTO 255
itwillbe changed to make surecontrol still passes to
the correct place. If line
255
han been
renumbered so 120, then the above line will be altered
to
GOTO 120
