The failing line in the script is :
%hash = (^69^22.... => 123)
Perl (5.8.6) complains when it reads thus : "Unrecognized character \x69".
If I just write \x69\x22, perl doesnt understand that I am implying the character 'tau'.
Is there a way to display the 'tau' character as a bareword, without interpreting it as "\x69\x22", on a ebcdic platform ?
Thanks for all the help, Rajarshi.

Off the top of my head, every "token" of text in Perl is either:
* an operator: +, *, =~, s///, ..
* a built-in function: chomp(), map(), grep()
* an imported function or method from a module: $cgi->param()
* a user defined subroutine or method: do_stuff_with()
* a string: "including" qw{ things like }, qq[ this ], 'or', "this"
* a bareword: FILEHANDLE, etc
I may have missed a class or two, but that's most of them.

A non- operator / function / method / subroutine / string that includes one or more UTF8 characters.

Well, if used exactly as you have it there, it's a string, because it's wrapped in double quotes. If you just had
\x69\x22
by itself, then yes, it would be a bareword.
