Thank-you Christopher
Of late I've been using Cybero's Javascript for QC guide. I need to
cast the net a bit wider again I guess. That answered my question
though, cheers.

instanceof and typeof.
var aThing = 42;
function (__boolean isBool, __string type) main (__number patchTime)
{
var result = new Object();
result.isBool = (typeof aThing == "boolean");
result.type = typeof aThing;
return result;
}
type = "number" in this case (so isBool is false). If you change it
to "aThing = false", or "aThing = "hi mom"", you'll get "boolean"
and "string" respectively. (you can also check for arrays and
objects this way, I think).
There are thousands of websites devoted to teaching JS so you can
make gaudy animated cursors on webpages and whatnot -- you can glean
a ton from such sources.
