If oapp.cust is the only reference to this object, making it .NULL. removes all references... More general, assigning any new value to it will release the previous pointed object. In particular, if you have oapp.cust=newobject('othertypecust','customers') again, the old object will be released automatically.

>(2) does oapp.cust=.NULL. completely remove all references to cashcust from meory??. I ask the second question because I will be calling the oapp.cust=newobject('othertypecust','customers') many times. Thank you for your help in this..
