Re: [Condor-users] Newbie question about Perl programs

["Darin Kalisak" <whognu@xxxxxxxxx>]

Thanks for the additional info.  Is it fair to say, then, that for
technical reasons, only .bat and .exe files can be submitted to condor
as executables in a Vanilla Windows environment?

Oddly, the batch file I submitted that did work *was* able to call the
program as an executable.  (I'm not arguing the point, just making an
observation.  My ignorace about OS inner workings is monumental.)  I'm
eager to try adding a Linux machine to my pool.  Maybe I can use it to
convince the powers that be to start buying more of them.
