I would just store them in a sequence. Something like this:

sequence controls
   controls = {{},{}}

procedure add_control( sequence name, sequence control )
   controls[1] = append( controls[1], name )
   controls[2] &= createEx( ... )
end procedure

function get_control( sequence name )
integer i
   i = find(name,controls[1])
   return controls[2][i]
end function

I don't think the overhead would be unwieldy on a modern PC.

Be sure to investigate Derek's awesome alternate method of creating
controls ("newUIObj"). See this:

   http://www.users.bigpond.com/ddparnell/euphoria/Docs/EVENT.htm#STARTAPP

I think Win32Lib should deprecate the old way. :)

The newUIObj functionality is very versatile. You could read whole
interface systems from a text file (or database!)... but there's a lot more
to it.

Actually, now that I've typed all this up... Looks like the newUIObj
feature already has provision for calling named controls... So, either use
what I said above with the "old way," or go with the new and improved way.

Derek, you really should trumpet newUIObj+startApp. :)

I wonder how easy it would be to make the IDE output newUIObjs instead of
create()s... :)
