Gerald,
In your vbscript, you can use "Script.ReturnValue = i", where "i" is an integer variable, to return a value to PlanetPress. The function ExecScriptFile is actually a function that returns an integer.
So in a PressTalk object, you could say:
define(&i, integer, 0)
&i := ExecScriptFile('C:\\myscript\\script.vbs', '', 1)
show(inttostr(&i))
And then in your vbscript, you can use:
Script.ReturnValue = 1337
With this, the "show" command in your PressTalk object will display the number "1337".
Hope that helps.
Regards,
Rapha
