Erlier in this newsgroup, there was someone mentioning that it is possible
to call external applications from forms. I believe I saw something
similar mentioned somewhere else. Can anyone point me to a sort of
"HelloWorld" example on how to do this, with data exchange in<->out of the
form ?

I really don't know where to start. Now, someone could ofcourse point me
to javacript for dummies or something, but what I could use, is a somewhat
more specific approach. A bit like the formscript coolsolution.
