[jawsscripts] Re: Variant data type in JAWS scripts

Variant is an undocumented variable type in JAWS scripting that I have
often used in order to obtain a degree of polymorphism.  I boldly
assume that you are taking interest in this after examining some of
the BX source code. <grin>

In any case, yes, the compiler doesn't fully support Variant, but it
does partially.  You can't say "let v = 0," but you can say "let v =
vcast(0)" if vcast() is defined as

variant function vcast(variant v)
return v
endFunction

olutil.jsl contains a version of that little piece of glue, under the
name olVCast().

I would like to learn more about how the variant data type may be used in
JAWS scripts.  Apparently, it may be used as a parameter or return value,
as well as a local or global variable.  When I tried to assign a number to
a variant variable, however, the compiler complained about a type
mismatch.  I find no functions specifically for converting to or from
variants.  Does anyone know what conversions are done automatically and
what conversions can be done with existing conversion functions like
IntToString?
