in reply to Re: Using Multiple Versions of ActivePerl
in thread Using Multiple Versions of ActivePerl, or I Want to Use ActivePerl 5.8.0 But Not Break My ActivePerl 5.6.0

I've done that as well, but if you keep reuse the same shell for a while, switching backwards and forwards, you can run reach the limit of what the shell will allow. And if you compile perl yourself, the paths can be quite long with the default options. I've set up a couple of batch files to call whatever perl I want:

:: perl580.bat @echo off d:\dev\perl\5.8.0\bin\MSWin32-x86-multi-thread\perl5.8.0 %*
> perl561 # runs perl5.6.1 > perl580 # runs perl5.8.0

I have similar batch files set up for perldoc et al.
