s from the file by suppressing details associated with keeping track of external REP locations and file positions. In a rep library, each external REP has an associated number by which it is known to both the library and the library user. 5 .5 Except ion Handl ing In Section 4, no method of handling exceptions was suggested. We now give Fortran implementations for two alternate methods: preconditions and signalling. A precondition is a condition which must be satisfied at the time an operation… CONTINUE READING
