Transfers control to a variable that was assigned a label.
Syntax
GO TO integer-variable [[,] (label-list)] |
- integer-variable
is a scalar variable of default type integer.
- label-list
is a list of statement labels, separated by commas.
Description
The assigned GO TO
statement transfers control to the statement whose label was most
recently assigned to a variable with the ASSIGN
statement.
integer-variable must be given
a label value of an executable statement through an ASSIGN
statement prior to execution of the GO TO
statement. When the assigned GO TO
statement is executed, control is transferred to the statement whose
label matches the label value of integer-variable.
label-list is a list of labels
that integer-variable might assume.
integer-variable must not be an
array element or an integer component of a derived type.
The use of this statement can hinder the ability of the compiler
to optimize the program in which it occurs.
Examples
