To all the does the UpdateNameList, of cursorsetprop() have a maximum length?

After I add about 8 field names with asocciated SQL table name, this propertie blows up.

Here is a list of names that work:

=cursorsetprop("UpdateNameList", [Dockey dbo."trandet"."dockey",;
prodid dbo."trandet"."prodid",td_status dbo."trandet"."td_status",;
prodid dbo."trandet"."prodid",prodtype dbo."trandet"."prodtype",;
pending dbo."trandet"."pending",mbpend dbo."trandet"."mbpend",invitem dbo."trandet"."invitem"])

When I add another field as the one below:

dbbatchno dbo.trandet.dbbatchno

The prpertie blows up.

Any ideas?
