When I first started learning ooREXX (not that long ago, and I still don't know
it well) I read that bit about "messages" that are apparently sent to methods
and properties and was confused. My only object-oriented language at the time
was VB (the VBA and VBS varieties), and I thought of methods as merely
specialized function calls.
Really I still do, I guess. I told myself provisionally that the tilde in
ooREXX is simply the equivalent of the period in a VBA method or property
reference, and although I'm pretty sure that isn't the whole story I was at
least able to continue on that basis. I keep reading descriptions like the
below, though, thinking that more will sink in eventually.

* The tilde (~) is the ooRexx message operator; one can send messages to any
value/object/instance
in an ooRexx program. Left of the tilde is the receiving
value/object/instance/receiver (these
are synonyms), right of it the name of a method routine that conceptually
the receiver is
supposed to look up and invoke on behalf of the programmer. If the invoked
method routine
returns a result one can immediately send it a message too, if needed.
