One (and only one) of our users is getting a Code 67 (Too Many Files) Error on an OPEN Statement. The program is running as a DOS App under Windows in a network environment. We ahve verified that the two documented reasons for the error -- too many open files versus FILES=N in CONFIG.SYS, and more than 255 files in a directory -- are NOT the case. Any ideas for other possible reasons for the error (including the possibility that a wrong Error Code is being transmitted)? Thanks. [sig][/sig]
