Well, that __would__ be nasty <grin>.

Or even the very old UNIX "compress". zip is not really designed for "on the fly" compression and decompression. compress and gzip are for "stream" compression. I sometimes use them myself like: gzip file | ssh u...@remote 'gunzip >file' when I run over a slow link. That compresses the source file, piping the data, as it is being created, into ssh, which establishes a connection to "remote" as "user", then pipes the data coming over into gunzip which write it to "file", via redirection. In any of these cases, "something" need to do the translation from EBCDIC to ASCII. Either before the compression or after the decompress, but before writing. Like: gzip ebcdic.file | ssh u...@remote "gunzip | iconv -f ibm-1047 -t iso-8859-1 |tr '\025' '\n' >" Note in the above, that the iconv "messes up" in that z/OS UNIX delimits with an NEL (0x15) instead of an LF. So on the ascii side, the 0x15 needs to be translated into an LF (\n). The ASCII file transfer does this for you. But a binary, followed by a normal iconv, does not. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
