Important Notice
The pages on this site contain documentation for very old MS-DOS software,

If you're looking for up-to-date documentation, particularly for programming,
you should not rely on the information found here, as it will be woefully
out of date.
GOTO (Assigned GOTO)

─────GOTO (Assigned GOTO) ──────────────────────────────────────────────────
Action
Transfers execution to the statement label assigned to <variable>.
Syntax
GOTO variable [ [,] (labels)]
Parameter Description
variable An integer variable. The <variable> must have
been assigned the label of an executable
statement in the same program unit.
labels A list of one or more labels of executable
statements in the same program unit. Separate
multiple labels with commas.
A <label> may appear more than once in a list.
Remarks
GOTO statements may not transfer control into a DO, IF, ELSEIF,
or ELSE block from outside the block. The $DO66 metacommand can
override this restriction for DO loops.

Examples
ASSIGN 10 TO n
GOTO n
10 CONTINUE
The following example uses an assigned GOTO statement to check the
value of clearance:
$DEBUG
INTEGER view, clearance
C Assign an appropriate label to view:
IF (clearance .EQ. 1) THEN
ASSIGN 200 TO view
ELSE IF (clearance .EQ. 2) THEN
ASSIGN 400 TO view
ELSE
ASSIGN 100 TO view
END IF
C Show user appropriate view of data depending on
C security clearance.
GOTO view (100, 200, 400)
C If view had not been assigned one of the valid labels
C (100, 200, or 400), a run-time error would have occurred.
100 CONTINUE
