1. OOP example

Thank you for answering my questions about OOP.
Your example:
call_proc(foo[talk], {})
What was the code that led up to this point? I understand that foo is a
class (a combination of a routine and variables as you explained) and talk
is the routine within it but how did you "make" the class?
I am having some trouble understanding because this is an area of Euphoria
that I haven't explored yet.
Thanks,
David S.

100% correct.
You could also emulate variables:
constant TALK = 1, HELLO = 2
procedure talk(sequence s)
puts(1, s)
end procedure
integer i
i = routine_id("talk")
sequence foo
foo = {i, "Hellow World!"}
call_proc(foo[TALK], {foo[HELLO]})
