I will extract your code and do some tests.

It doesn't matter in the code you wrote because you used a literal string, but if you say open FH, $file or die "could not open $file: $!"; expecting FH to be a read filehandle and $file contains the filename ">important", you will wind up with a write filehandle. Specifying the type of filehandle you want separately from the file is an important safety feature. Using the old version of open is a bad habit you should not develop. You should know it exists (like many of the other bad habits left over from earlier versions of the Language) in case you run into code that uses it, but you shouldn't use it yourself. I would also strongly recommend using lexical filehandles instead of the old bareword style for similar reasons. -- Chas.
