1  GOTO
   Transfers control to a labeled statement in a command procedure.

   Format

     GOTO  label
 

2  Parameter
 

label

   Specifies a label of 1 to 255 alphanumeric characters that
   appears as the first item on a command line. A label cannot
   contain embedded blanks. When the GOTO command is executed,
   control passes to the command following the specified label.

   When you use a label in a command procedure, it must be
   terminated with a colon (:).  If you use duplicate labels,
   control is always given to the label most recently read by DCL.
 

2  Examples

   1.$ IF P1 .EQS. "HELP" THEN GOTO TELL
     $ IF P1 .EQS. "" THEN GOTO TELL
        .
        .
        .
     $ EXIT
     $ TELL:
     $ TYPE SYS$INPUT
     To use this procedure, you must enter a value for P1.
        .
        .
        .
     $ EXIT

     In this example, the IF command checks the first parameter
     passed to the command procedure; if this parameter is the
     string HELP or if the parameter is not specified, the GOTO
     command is executed and control is passed to the line labeled
     TELL. Otherwise, the procedure continues executing until the
     EXIT command is encountered. At the label TELL, a TYPE command
     displays data in the input stream that documents how to use the
     procedure.

   2.$ ON ERROR THEN GOTO CHECK
        .
        .
        .
     $ EXIT
     $ CHECK:  ! Error handling routine
        .
        .
        .
     $ END:
     $ EXIT

     The ON command establishes an error-handling routine. If any
     command or procedure subsequently executed in the command
     procedure returns an error or severe error, the GOTO command
     transfers control to the label CHECK.
