Informix SQL is trying to write the current SQL source file into a temporary file for editing but received an unexpected operating-system return code. Look for operating-system error messages that might give more information. On UNIX systems, possibly your account does not have write access to /tmp or the directory that is named in the DBTEMP environment variable, or the disk might be full. With Version 5.01 and later, the IBM Informix SE database server uses the DBTEMP environment variable, but IBM Informix Dynamic Server and IBM Informix OnLine Dynamic Server do not.
