Jean-Claude,
First, please do not "top post" on this list. (See
http://en.wikipedia.org/wiki/Top-posting#Top-posting for
more details.) Please use the usenet, or "bottom posting" style.
Second, be sure you have downloaded the files in "binary" (except
for DEBIAN EXEC) as opposed to "ascii", "ebcdic", or "text" mode
(depending on the method of download). This is important to avoid
unwanted (and fatal) ASCII to EBCDIC translations and also to avoid
linefeed or carriage-return/linefeed sequences being added. Make
sure the files are downloaded from the "generic" subdirectory,
not the "tape" subdirectory.
Third, just for grins, try using the unmodified PARMFILE DEBIAN file.
If that works, you can abort the installation and try again with a
modified one.
I think that is the most likely cause of trouble. It is VERY important
that the last used charater be followed by a linefeed (X'0A' in ASCII,
X'25' in EBCDIC). XEDIT tends to remove this terminator. The line must
be filled with nulls (X'00' in either code) after the terminator out to
80 bytes. (Use "SET NULLS ON" in XEDIT.) I would issue
SET VERIFY OFF H 1 80
in XEDIT just prior to the "FILE" command to verify the trailing linefeed
and trailing nulls.
