If I substantiate a form as:
oCalendar = NEWOBJECT('frmCalendar','Misc.vcx')

Then Initiatialize it and pass parameter EMPTY(dbirthdate):
oCalendar.Init(dBirthdate)

Then Show the form:
dBirthdate = oCalendar.Show()

The RETURN in the form classes UNLOAD doesn't get returned to dBirthdate. Is there another way to amend the value of dBirthdate, obviously my SHOW() syntax is incorrect.
