I have not used MOM, as I mentioned, and all I could remember was the
try .. catch structure in the same paper that discussed MOM. If I
remember correctly, it was introduced quite a few versions back, was
it version 5? I do not have a version that has MOM; however, it is
unlikely that you would encounter any nasty surprises with it.
I am encouraged to sense that you seem pretty excited about this ... I
find it very welcome to find people adopting techniques that do not
belong to traditional APL but from an APL development environment.
Why don't you investigate it a little more and then write up your
findings for VECTOR, the journal of the British APL Association? Have
a look at www.vector.org.uk; this has all the contact details (you
need to contact Stephen Taylor). You could also post the article in a
common format (rft or pdf) unto the APL2000 website forum
http://forum.apl2000.com/.
When you have, perhaps you can answer a question: can you persist i.e.
save a MOM onject or it is a session bound object only?
Interestingly, I am presently looking into JSON, primarily from APL
+Win. JSON = JavaScript Object Notation. This is a little like the MOM
example you give but uses COM syntax. To give you a (simple) glimpse
of what this is:
a<-'var myObj = {name: "John", DOB: "01/01/1980"};'
'APL' []wi 'Create' 'MSScriptControl.ScriptControl'
'APL' []wi 'xLanguage' ''
'APL' []wi 'xLanguage' 'JavaScript'
'APL' []wi 'XAddCode' a
'APL' []wi 'XEval' 'myObj.name'

JSON is meant to be {simpler} XML and as a mechanism for data-
interchange. It does handle APL literals, scalars, vectors and nested
arrays: ironically, JavaScript does not intrinsically sup****t multi-
dimensional simple arrays but there are ways to coerce this.
Thank you for your comment about the book. (Someone) need(s) to write
one on Visual APL, the other great product produced by APL2000.
With APL, you have chosen the best language to learn; however, it is
just one of the many languages you can learn. For instance, the
Express version of C# 3.0 is available as a free download.
