rename a file in win98

[Chris Zampese]

Just wondering if anyone has any bright ideas on how to rename a file in Win98.  I 
have tried the following...

my $old="C:/sentslips/sentslipstemp.txt";
my $new="C:/sentslips/sentslips1.txt";
    
rename($old, $new);

But no luck, the sctipt runs without errors (I am running with the -w switch and use 
strict)
 
     Thanks for your help, 
                        Chris
