This and the Code Pages observation Dave Stuart made ... no, no, MD5 (and other hashes) is a binary checksum. It should ignore record boundaries. (Discussion grows long from here.) If record boundaries are significant, then you're talking about some plain text file which must be translated perfectly before being subject to hash/checksum. Byte-for-byte MD5 (and other) checksum should match between CMS and Linux. Witness the many download sites and public repositories which include MD5 and/or SHA-1. The hashes are excellent for assuring the transfer did not clobber the file. I agree there should be better "text checkers", but was shot down in the days when MIME was first introduced. (I wanted them to ignore linear white space in some comparisons. CMS to date does not support truly empty records in minidisk or SFS files. Makes email quirky to process. What a pain.) But MD5 is binary. -- Rick Troth Senior Software Developer Velocity Software Inc.
