Thanks TGI, I can clearly see your point now. Indeed, 0 is perfectly possible user input, but evaluates to false in my test! A perfect way to get fired!

Oh, about the Camel, it has never left my desk the last 2 months! My brother bought it to me as a present, and I am reading every inch of it. It is not only the language details, but programming concepts in general that make this book a real treasure. It is a misconception that scripting languages like Perl do harm to programmers. This book has enlightened me on the contrary.

[Cosmic37]: I guess it is searching for the string "$mydt"
[Corion]: Indeed cool, erix ;)
[Cosmic37]: rather than the value of $mydt which is a date time strong such as 2016-01-01 12:30:56
[Corion]: Cosmic37: No, but maybe $mydt doesn't contain what you think it does, or it contains characters that are special in a regular expression? Try if( $line =~ /\Q$mydt\E/) { ... for a literal match
[Cosmic37]: I mean string grrr
[Corion]: Maybe add an else branch in which you print what the values of $line and $mydt are?
[Cosmic37]: ah thank you I will try
[Cosmic37]: you are right $mydt did not contain what I expected... :-D I will now think :-D
[Cosmic37]: crunch...grind... whirr...gnashing metal crunching cogs...
