Well, just for the sake of TMTOWTDI, how about: C:\>perl -le "$_ = q[GNU tar 1.20 is available]; print" GNU tar 1.20 is available C:\>perl -le "$_ = q[GNU tar 1.20 is available]; s/([.\d]+)/$1+0/eg; print" GNU tar 1.2 is available -- -jp I wish I would have a real tragic love affair and get so bummed out that I'd just quit my job and become a bum for a few years, because I was thinking about doing that anyway. deepthoughtsbyjackhandey.com
