in reply to Adding Default Values [for BEGINNERS]

Thanks. Those ideas seem to work, and the funny thing is, i do know about chomping and forgot to do it. I use -w when calling the scripts.

One pickle.. I am using winXp, and ActivePerl and when i add USE STRICT, my script blows up on me with GLOBAL SYMBOL error statements. It pretty much complains about everything from line 22 and down, "requiring explicit package name..." for the different variables the script encounters.

Also, after adding the chomp, and pulling out the \n print, I have to hit return twice, but it does use the provided default. Any thoughts?

Again, thank you everyone.

    Adding use strict; requires that you declare variables using my. For example in:

      my ($Drivers, $Points_Rank, $TotalPts, $Behind, $Starts, $Poles, $Wi
+ns, $Top5, $Top10, $DNF, $Winnings) = split /\,/, $line;

    the my is required.

    For each and every occurrence of <STDIN> you should have to hit return once (and once only).
    In making your changes have you inadvertently introduced another <STDIN> ?

    Cheers,
