1. Question for Robert Craig
Rob, I have been using *return* clause not only in functions, but also in proc
edures.
Mainly in recursive routines, and, occasionally, as a shortcut from complicated
elsif
structures. It seems to work, but is it legitimate, or more importantly, is it g
oing to
be ok in future releases of Euphoria? Jiri

Yes, executing a return statement in a procedure is totally
legitimate. It has been there since day 1, and will
always be there. When you return from a *function* you
must supply a value to return to the caller e.g.
return 9 * length(x)
but when you return from a *procedure*
you can just say:
return
Control is passed immediately back to the
caller of the procedure. No value is returned.
Only *functions* return values. In practice it seems
like most procedures terminate by simply reaching
"end procedure", but you can end earlier by executing
*return*.
