Having just done this, I speak from experience....
Almost every file transfer product will transfer either text or binary.
Most have a feature that will make a choice for you. I used the "make a
choice for me" option and wound up scrambling the three files I had
transmitted. I changed the format to binary and everything worked as it
should.

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.

This x'69737970' is really (once high bit is added back) x'E9F3F9F0' ie 'Z390'
ie something that pkzip for z/OS inserts.

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. Paul.
