IBM usually recommends AMATERSE. Do TERSE envelopes use any sort checksum for verification? You will need to investigate: o Does the RDF provide support for data on DVD? o Does the RDF provide support for verifying checksums? The base z/OS provides the POSIX cksum(1), and ICSF supports SHA-1, perhaps others, and MD5 is widely available as source in an RFC and as executables for various platforms. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
