OpenEuphoria

Dumb question by a beginner

Hey everyone.  I just started with Euphoria (got tired of struggling with C
and C++) and I'm basically a rookie here.  The reason I had trouble with
C/C++ was that I was able to get the compiler to do what I wanted less than
half the time, no matter how many examples I explored!  And basically,
screwing around with simple code is how I get a grasp of a language and learn
to use it for myself.
  Well, I've been reading the documentation, and now I'm trying to get simple
routines to run - ones that originate completely from myself.  Right now, I'm
tinkering with functions and procedures, so forth.
  Here's one I'm sure everyone understands but me.    I don't seem able to
find any directions, or examples that I can fathom, of how to pass
information back and forth between functions, or from the main program to a
function and back again.
  As I understand it, a EU procedure is when you don't need any information
returned to the rest of the program, while a function is used when you do.
I'm not clear on what the uses there are for a procedure if all you can do is
pass it a value, have it work on the information, then get nothing back
(which makes me question my understanding of it).
  But regardless, my experiments with functions have only yielded me errors.
When I look at other programs, I don't quite see how the main program is
passing information to the function, nor do I see how the main program is
receiving this information back - where does it store the data, etc..  So
then, how do I correctly pass this sort of information back and forth between
procedures/functions?  Perhaps someone could send me some simple code, and
tell me what the assignments actually are in the example, since I'm not
getting it from the existing examples I've seen?  
  Perhaps I'm just not reading the documentation correctly, or I'm
overlooking some existing examples.  There seems to be some hole in the
documentation and such that comes with EU, to me.  Which, again, makes me
wonder what I'm missing.  I also don't seem able to locate any index of error
codes and messages.

 THANKS to everyone and anyone in advance.  I hope to be contributing to the
group soon, if I can move beyond the realm of "trying to get a basic
understanding..."
  Hopefully, I won't be asking too many more easy ones.
