RE: Invoking a program which is not in the existing application.

Martin,

What I wanted is, accept the value on the screen(from the field(X) on which
the cursor is) and display another value (which is based on a calculation of
the earlier field(X)/value). I would not be bothered for the validations of
the field and so a trigger would not suite the requirement.
And as someone on the list suggested I can invoke an attention-key-program
to do this. But how is that I would pass the value(from field(X)) in the
original application into the new attention-key-program.
