This seems very plausible to me. I took the extracted archive and re-archived it with 7-Zip (the interface is unfamiliar to me, but I mastered it.) I clicked zip and deflate. The archive is 1% smaller than that produced by Info-zip. I extracted it again with z/OS 2.2 "jar". (It took a l-o-o-o-ng time again.) That extracted archive again compared as identical to the one extracted previously.
I wonder how long it will take IBM Docs to recover from such a simple finger fumble? But I believe 7-Zip would have created an archive with suffix .7z. Did someone foolishly rename it, blithely ignoring Windows' warning that "You really shouldn't want to do that; it can make Bad Things happen"? And someone further compounded the mess by associating ".zip" with 7-Zip, concealing the error. Should I at least write to the 7-Zip guys and say it would be a courtesy to the supplier and the customer to issue a prompt, "This appears not to be a .zip archive. Do you wish to continue?" -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
