Chapter 10 365
GO TO (assigned)
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
ASSIGN 10 TO out
GO TO out
