I have a problem with Access97 not working properly when entering new

records using a sub form, i.e. entering a new order/orderlines or master
and
detail tables.  The problem is caused by a SQL statement that Access97
makes
involving NULL.  The syntax that fails is "column_name" = NULL.  The
following attachment was provided by -Jose'-.  It contains a very small
enhancement to gram.y that will allow Access97 to work properly with sub
forms.  Can this enhancement be added to release 6.5?

 <<gram.patch>>
Thanks, Michael
