16 # This procedure creates an option button named $w and an associated
17 # menu. Together they provide the functionality of Motif option menus:
18 # they can be used to select one of many values, and the current value
19 # appears in the global variable varName, as well as in the text of
20 # the option menubutton. The name of the menu is returned as the
21 # procedure's result, so that the caller can use it to change configuration
22 # options on the menu or otherwise manipulate it.
25 # w - The name to use for the menubutton.
26 # varName - Global variable to hold the currently selected value.
27 # firstValue - First of legal values for option (must be >= 1).
28 # args - Any number of additional values.
