Shell Programming and Scripting

Hi, I'm having the following problem with the unix sdiff command.
for example if I try sdiff <filename 1> <filename 2>
Where filename 1 and filename 2 contain really long pathnames that I need to compare.

The output I get will be 139 characters long which is the default.
But an output of 139 characters is not enough to show the full pathnames,
so to fix this I use the -w option:

sdiff -w 1000 <filename 1> <filename 2>

When I do this on a unix machine using a tcsh shell I fix the problem I was having as the full path names are now present in the output lines.
For example:

/root/sub1/...<longpath> .../subN/index.html@@/main/R1A/R50/R56F/2 |
/root/sub1/... <longpath> .../subN/index.html@@/main/R1A/R61/2

But when I do this also on a tcsh shell but by connecting to a unix environment using exceed from windows, the shell inserts garbage into the empty space in the output line:
For example I could get an output like the this:

/root/sub1/...<longpath> .../subN/index.html@@/main/R1A/R50/R56F/2 *&&$£""5he3("£diff -b Wrong line length %sIllegal arguement


and the command fails.

I've attached the output of typing env in the shell thats working and in the shell that is not working, in case this is of use.

Does anybody have any idea how to solve this problem?
any help would be appreciated.
