1 GOTOTransfers 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.
