I've looked at David's example. I just made up something similar. I
tried to keep the syntax closer to what Udo wanted. I see no obstacle
in IDL to call multiple embedded procedures or functions. However,
after several levels are embedded, it is really hard to understand what
the code is doing, in my opinion.

;******************
pro test

argument = 2.0
forward_function func1, func2
proc, func1(argument)
proc, func2(argument)

end

;******************
pro proc, input
; Perform action expected from PROC
print, input * 10
end

;******************
function func1, argument
return, argument + 1.
end

;******************
function func2, argument
return, argument + 2.
end

;******************
