Equivalence to the SuperCard function call "via" object

[Ken Ray]

Joel,

The value() function is what you need, but to include parameters, you
need to include them like a "do". That is, if the parameter is a
variable you need to "&" it. I ran your test like this:

Script of button 1:
-------------------
on mouseUp
  put "Hello" into tMyVar
  put "Goodbye" into tAnotherVar
  answer value("getSomeData(1,the date," & tMyVar & "," & tAnotherVar &
")",btn 2)
end mouseUp

Script of button 2:
-------------------
function getSomeData p1,p2,p3,p4
  -- p1 is a number, p2 is a date, p3 is a string, p4 is a string
  return p1&&p2&&p3&&p4
end getSomeData

When I clicked button 1, I got:

  1 7/7/03 Hello Goodbye

(which is what I expected). So variables are not evaluted before they
are sent to the object - you need to force them to evaluate by "&"-ing
them as in my example above.

Does this help?
