Function:
Branches
to
a specified location according
to
the branch condition.
Parameter:
Branch condition:
Line No.:
Program area No.:
Explanation:
Numeric expression. Values below the decimal
point
are discarded.
1
to
9999.
0
to
9.
I)
Branches according
to
the integer part
of
the value in a branch condition
expression. Branched locations are allocated sequentially according to
ON
A
GOTO

A=2
A=J
2) When the value
of
the expression
is
smaller than 1, or when an appropriate
branched location does
not
exist, the next statement
is
executed without
branching.
3)
As
many branched locations
that
can fit
on
one line can be written.
Example:
10
INPUT
''A=''
,A
20
ON
A
GOTO
100,200,300
