I don't think _accessing_ them is especially tricky. Making sense of them is another matter, and I think, application-dependant. What fields are character and so should be translated? What fields are binary? Should we handle endiannes "just in case" someone takes the files off to a peecee? What about decimal fields? Floating-point? Better, I think, to implement access routines (a server) on the zOS system and chat to it via TCP/IP or UDP/IP. Pass character data in ASCII, binary integers in NBO. Quite likely, you can do it in REXX on zOS of performance isn't an issue. -- Cheers John.
