END
RETURN
wm_contextmenu:
guiaddmenu('List')		
RETURN
toggle_menu:
IF sw_toggle = 0 THEN
	DO
		SAY 'Setting a MARK for toggle_menu'
		guisetmenuopts('Toggle_menu', 'MARK') 	
		sw_toggle = 1
	END
ELSE		
	DO
		SAY 'Clearing toggle_menu'
		guisetmenuopts('Toggle_menu', '') 	
		sw_toggle = 0
	END
RETURN	

Run the script, right-click on the TEXT text and select the toggle popup menu. I'm getting an undefined control in the toggle_menu procedure. Is this a bug ?

As soon as a popup menu's item is chosen, then the pop-up menu is destroyed. You can't change the state of something that no longer exists.

I presume what you're trying to do is alter the state of a item before the popup menu is shown? As I recall, you do that from an INITMENU event handler.
Message3. It's not a problem for me

I want to be able to present a popup menu to the user that allows him to toggle a menu item on this menu (and for this to be shown next time).

I guess the answer is that I have to note if he selected the toggled item, save this fact, and show the item as toggled the next time I show the popup menu.

Yes, that's it. The INITMENU event is there to initialize any menu items, based upon the (changing) state of your variables, before the menu is shown.

For example, RPC uses this to disable various Debugger menu items, depending upon whether a script is loaded, whether a script is running or paused at a breakpoint, etc.

run through a procedure called WM_INITMENU (after it's run through wm_contextmenu), but I couldn't figure out how to affect the toggle mark on the menu option. Any attempts to guisetmenuopts failed miserably
