HP Fortran statements
GO TO (computed)
GO TO (computed)
Transfers control to one of several labels.
Syntax
GO TO ( label-list ) [,] arithmetic-expression
label-list
arithmetic-expression
Description
332
is a list of statement labels, separated by commas.
is a scalar integer expression. As an extension, HP Fortran also allows the
expression to be of type real or double precision.
The computed GO TO statement transfers control to one of several labeled statements,
depending on the value of arithmetic-expression. Afterarithmetic-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
