Thank you, I lost my line during the cut/paste excercise and had to retype it. The -w is equivalent to the use warnings; isn't it. I often just leave the #! line out from my win32 scripts.

Thank you,
Greg W.

    It's not quite the same. -w is actually equivalent to BEGIN { $^W = 1; }. There biggest difference is that -w will affect included modules, whereas use warnings; only affects the current scope (block or file).
