This stuff is prepended to the resultant string of the known files SYS$OUTPUT and SYS$ERROR. The system service manual entry for trnlog_s explains what must be done to get rid of the binary garbage. Your assign_s system call should then succeed. This problem only occurs when you use one of the known file logical names. Joe Sventek
