How to overwrite existing file?

[Michael Lemke]

I just can't figure this out: how do I overwrite an exisitng file
without creating a new version?  I.e., if x.;1 exists I want perl
to use that and replace the contents.  But when I try that 
I get:

$ perl -e "open(X,"">x.;1"") || die; printf X ""blabla"";
Died at -e line 1.
%RMS-E-FEX, file already exists, not superseded


I couldn't find anything in perldoc perlvms or the web,
please help.

Thanks,
Michael
