>PKZIP supports compression of files over 9 exebytes in size. We went from PKZIP to ZIP/390, because of cost and support issues. ZIP/390 comes from DATA21 (www.data21.com).
Both companies support lines are only open 9-5, M-F (local time). DATA21 is in California, and PKZIP is in Phili (I believe). >I am sure that there are others as well. I cannot speak to file size. We rarely had files over 500 Mb. The only 'flaws' I've found in ZIP/390: 1. You cannot add a file to an existing archive. 2. You cannot compress VSAM; this is an added cost feature in PKZIP. The other problem with PKZIP/MVS, beside the ones I mentioned above, is archiving PDSE's. This is automatic with ZIP/390 and a cost feature with PKZIP. - Too busy driving to stop for gas! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
