I used to love Rexx too. but, after I had been exposed to some OO
methodology I had to write a UI type app with potentially nested
screens.... And soon found myself appreciating OO's value. You can
build data structures as complex as you like with stems but without real
OO you have to manually, tediously, identify the received structure in
the callback function then decide what to do with it. OO makes this
more or less automatic with super/sub classes handling most variants of
the structures. As often as not you do not even need the callback
function itself, just a method for the class ... at the hightest level
in the heirarchy which is reasonable so you minimize the work you do for
the subclasses.
