By method, you probably mean a function. You probably source it (.) to make the function accessible from the current shell. You can call ksh from Perl, which would source the script with the function and run the function: 
$output = qx{ /bin/ksh -c ". /path/xyz.ksh ; xxxx arg1 arg2" };
print $output;
