SYNOPSIS        sum name  ...

DESCRIPTION     sum sums the contents of the bytes (mod 2^16) of

                one or more files and prints the answer in octal.

                A separate sum is printed for each file speci-

                fied, along with the number of whole or partial

                512-byte blocks read.

                In practice, sum is often used to verify that all

                of a special file can be read without error.

FILES           none

DIAGNOSTICS     "oprd" if the file cannot be opened; "?" if an

                error is discovered during the read.
