GoSub...Return Statement

Calls a subroutine that is indicated by a label inside a Sub or a Function. The statements following the label are executed until the next Return statement. Afterwards, the program continues with the statement that follows the GoSub statement.

Syntax:


GoSub label[:]

Parameters:

label: A line identifier indicating where to continue execution. The scope of a label in that of the routine it belongs to.

The GoSub statement calls a local subroutine indicated by a label from within a subroutine or a function. The name of the label must end with a colon (":").

      GoSub label
      ' statements
      Exit Sub/Function
