You need to use a RETURN something here in your method. Because you want to pass back two variables, I would pass an object back with two custom properties. Instead of your ? lines, use:

oReturn = createobject("custom")
oReturn.AddProperty('customerID',mytable.id)
oreturn.AddProperty('customername',mytable.customername)
return oReturn

From your program just use:
omydcom = createobjectex('mydcom','someothermachine')
oCustomerInfo = omydcom.Showrecord()
