I have a zip file that appears to have been produced using pkzip for z/OS. However, it looks like it has been transmitted using some sort of text protocol, because the high bit has been stripped from most bytes, and some other bytes appear to have been translated. e.g. I think x'0a' in the input file has been mangled to x'b6' on the way. Does anyone know what software would do a translation like that?
I believe these characters: > 0A 1060 > 0D 0 > 12 1044 > 14 0 > 15 0 > 1C 0 > 1E 0 > 24 1030 > 7F 0 are being mapped to these: > 81 576 > 9C 361 > A7 645 > B6 527 > BF 284 > E0 249 > E9 644 > F2 718 Except for x'0d' which I think is just being deleted. This belief comes from counting (see below) occurrences of the various bytes in a largish (80k) file. Here is a small file that shows the problem: 000000 504B0304 B6000600 08006455 22405746 PK........dU"@WF That x'b6' above should be x'0a' I think (that's more normal). Apparently some protocol doesn't think that x'0a' will make it through, so translates it in advance. 000010 30447A00 00002802 00000800 00005851 0Dz...(.......XQ 000020 46303130 38313510 310A4330 0C447740 F010815.1.C0.Dw@ ... 0000A0 504B0102 780BB600 06000800 64552240 PK..x.......dU"@ 0000B0 57463044 7A000000 28020000 08003401 WF0Dz...(.....4. 0000C0 00000000 01000000 00000000 00005851 ..............XQ 0000D0 46303130 38316500 30016973 79700006 F01081e.0.isyp.. This x'69737970' is really (once high bit is added back) x'E9F3F9F0' ie 'Z390' ie something that pkzip for z/OS inserts. 0000E0 00014000 00050002 10000600 04022800 ..@...........(. 0000F0 06005C00 08000700 05000001 00070006 ..\............. 000100 00004B00 05000740 0040000B 00064462 ..K....@[email protected] 000110 52707073 40404040 40404040 40404040 Rpps@@@@@@@@@@@@ 000120 40404040 40404040 40400A @@@@@@@@@@. Does anyone have any idea what protocol (ftp, sftp, winscp, kermit, connect:direct, http) would affect data in this manner? I've never seen mangling like that before. Thanks.
