cREVGeneral is an example of where recursion would be a problem. In the
common library there are getProp and setProp handlers that depend on lock
messages. The handlers intercept the message and in some cases need to
lock messages to get the system property before continuing (so a pass would

I guess I see your perspective. For me it’s totally the right and natural
thing.
It’s automatically reset at the end if the handler. Personally I’d go the
other way and say that if the lock messages were set command calls trapped
by anything above in the hierarchy should also not get executed.

Yes, for the purposes it was designed for (stopping the triggering of
system messages) the "lock messages" command is very useful.
The problem with getProp and setProp is that those triggers occur in
response to *custom* properties, not system properties.
As originally implemented (and as rem

Yes - thanks for pointing that out. So far I've found the behaviour of
lockmessages to be actually useful rather than an issue with
getprop/setprop - seems well designed to me.
The place where the syntax really shines is with functions calls rather
than commands - dispatch is quite natural for tha

While the getProp and setProp handlers would seem to lend themselves to
a lot of useful object binding opportunities, they require caution:
they're treated by the engine
When I was first exposed to arrays in Foxpro, I saw them as ordered blocks of
memory which could be addressed using integer values. Back then an array in
memory resided in a contiguous block of memory for efficiency, and were 2
dimensional, so a reference to an element was myArray(x,y) (if memor
Actually the use case was different. More of a generic way with nice syntax
to call remote functions. This is easier now with dispatch but still not
quite as elegant IMO as using virtual properties of models.
Let’s take an example that I currently use. Note that the rational here is
to avoid where

And yes thanks for suggested way around incompleteness. I still suffered

Aha. Clarity. I'd wondered if properties might be involved but hadn't
considered functions. Examples in the dictionary would be great.
