running system command
Trying to run system commands from ActivePerl on Windows.
I tried adding the following lines to my perl script to run commands,
but does not work. How can I run the commands.

$ENV{`PATH`} = `Windowssystem32:data_vcs:Program FilesGNUWinCvs
1.2`;
$ENV{`CVSROOT`} = `:pserver:myname@...:/u`;
$ENV{`CVSHOME`} = `data_vcs`;

$result = exec `cvs rdiff -D 04/01/2004 -D 05/11/2004 documentation
2>&1 | grep Index | sed "s/Index: //g" | grep .pdf$ >
pdfresults.txt`;

I can run the command from a dos prompt, starting with cvs rdiff, and
it works great. How can I run it from a perl script. I am not sure if
$ENV{`CVSROOT`} or $ENV{`CVSHOME`} can be set this way.
