Coding the Main routine

The Main routine is the main part of the program:

  #
  # Main
  #

	set app [VtOpen Example]

        set mainform [VtFormDialog $app.form -title "Kill"]

	CreateMenu $mainform
	CreateList $mainform

	VtShow $mainform
	VtMainLoop

1. VtOpen(VTCL) establishes the connection with the SCO Visual Tcl server.

2. VtFormDialog(VTCL) creates the first form of the program.

3. CreateMenu and CreateList fill in the form with widgets.

4. VtShow(VTCL) displays the form.

5. VtMainLoop(VTCL) gives control of the program to the user, and the program waits for events.
