Transfers control to one of several labels.
Syntax
GO TO ( label-list ) [,] arithmetic-expression |
- label-list
is a list of statement labels, separated by commas.
- arithmetic-expression
is a scalar integer expression. As an extension,
HP Fortran also allows the expression to be of type real or double
precision.
Description
The
computed GO TO statement transfers control to one of several
labeled statements, depending on the value of arithmetic-expression. After arithmetic-expression is evaluated (and, if necessary, truncated to an
integer value), control transfers to the statement label whose position
in label-list corresponds to the truncated value of arithmetic-expression.
If the value of arithmetic-expression is less than 1 or greater than the total number of labels
in label-list, control transfers to the executable statement immediately
following the computed GO TO statement.
Examples
index = 3
! Branch made to the statement labeled 30.
GO TO (10, 20, 30, 40) index |
