Put the list in a single string, like this:

=CursorSetProp("KeyFieldList", "mas_sqlkey,master")

>I am trying to change a cursor from SQL Server to be act like a remote view and I am getting an error on the keylist command.
>
>lnR = SQLEXEC(g_sql_h1,"select * from master order by mas_sqlkey", 'master')
>
>=CursorSetProp("Tables", "master", "master")
>=CursorSetProp("KeyFieldList", "mas_sqlkey", "master")
>=CursorSetProp("UpdateNameList", "mas_delet master.mas_delet")
>=CursorSetProp("UpdatableFieldList", "mas_delet")
>=CursorSetProp("SendUpdates", .T.)
>
>Any ideas?
