Al,
A bit OT, but I thought you might want to know that I've created in Minilang a
<call-simple-method-scoped> that allows you to call simple methods as reentrant functions.
Without <call-simple-method-scoped>, about the only way to do reentrant functions in Minilang was
to use services.
But note that <call-simple-method-scoped> does not have the parameters (IN/OUT) checking that the
Service Engine provides.

I just want to get the first <x> characters in a text string (which may be
shorter than <x>). Ideally, I want to break at a whitespace - more reason
for writing a special function.
I suppose I can just write a service to do it. I was trying to determine if
this (and maybe other string processing) should be added to the minilang
and
widget functionality.

What are you trying to perform if this were java?
