Help required regarding variable expansion in UNIX

Hello,

I have one variable coming from one file:
abc=$xyz/filename.txt where $xyz is defined in .profile file as say, /usr/dev/src

i am passing abc variable to one perl script as input parameter.
perl 123.pl -s $abc

But inside the perl script execution, the variable $abc is just expanding to $xyz/filename.txt but not to /usr/dev/src/filename.txt
Because of this perl script is failing saying $xyz/filename.txt file not found.

Can any one please let me know, how can i expand the unix variable completely before passing it to perl script.

Shell - KSH (/usr/bin/ksh)
OS - SunOS 5.10

Thanks in Advance
Vikas
