CSUM: a utility routine that writes and verifies checksums in disk files. [For CDC STAR and 7600]

Technical Report ·
OSTI ID:5271152

CSUM is a utility routine that appends a checksum to a disk file, and verifies that an existing checksum is valid. When CSUM ''writes'' the file, a machine-independent directory, which contains a machine-independent checksum, is appended to that file. When CSUM ''reads'' the file, it verifies the checksum and removes the directory. CSUM is available on the CDC STAR and CDC 7800 computers. Since the directory structure is machine-independent, CSUM is adaptable to any computer currently in use at the Lawrence Livermore Laboratory.
