AskGotoLine( )

The AskGotoLine method prompts the end user for a specific line number to display, then positions the file to the line nearest the one specified.

Implementation:

The ASCIIViewerClass invokes the AskGotoLine method from a RIGHT-CLICK popup menu. The AskGotoLine method calls the SetLine method to position to the requested record.

Example:

MyViewerClass.TakeEvent PROCEDURE(UNSIGNED EventNo)

 CODE

 CASE EventNo

 OF EVENT:AlertKey

   IF KEYCODE()=MouseRight

     CASE SELF.Popup.Ask()

     OF 'Print'

       SELF.Printer.Ask

     OF 'Goto'

       SELF.AskGotoLine

     END

   END

 END
