Hi,

I have the following requirement:

Do some work in any directory the codes are called. However, if the pwd is C:\, don't do the work there.

So, I've come out with the following program: 

use Cwd;
if (lc(cwd()) eq 'c:/')
{
   print "I'm not working on this directory!\n";
}
else
{
   print "I'll work on this directory!\n";
}
end;

However, there's a loophole here. If the user subst's C:\ with Z:\, and calls the codes from Z:\, it'll still run. It is not supposed to run, because Z:\ is effectively C:\.

Is there anyway to work around this subst, or even mapped drives?

Thanks in advance!
