			Line labels are often used to easily refer to [[form]] statements:

			1100 read #10,using Addressform: Mat Co$,City$,St$,Zc$,Mat Dd$
			1110 Addressform: form 3C 30,C 20,C 2,C 12,Pos 257,10C 18

New page

The '''Line label''' is an optional name for a program line. They are accepted at the beginning of all [[statements]] following the line number. The label may be from one to 30 alphabetic, numeric or underscore characters in length, but must begin with a letter. Each line label must be unique and immediately followed by a colon. Business Rules allows most statement and command keywords to be used as line labels. In the following statement, "LABEL_SAMPLE:" is a line label:

00900 LABEL_SAMPLE: Rinput #1, Select '2,40,Cr 10,[w]',Attr "[A]": Autoselect$

A line label can then subsequently be used in place of a line number to reference the line from a secondary expression. In the following example, the line label BIG is defined to represent line 120; it is then used as a line reference for the GOTO statement in line 300. (F1 is also a line label):

00120 BIG: Print Using F1: A$,T(5)
o

00300 GOTO BIG
