Thank you all for your comments!
Because I am used to C/C++ I do not 'like' the usage of variables and
subroutines before even declaration in a source code 'instinctively'.
This is, of course, my personal spleen which may change with more
experience in using Perl.

I want to take a win32 perl script to unix. Is their any document telling that what

Things you need to look out for are file locations, adding the shebang to
the top of the script (the #!/path/to/perl), directory paths that are
specified as \\ instead of / and any Win32 specific modules. Other than
that, test the script and see if it breaks...

Hi,
I've got a number of elements that are specified in a hash.
I need to find out the number of elements in the hash.
Is there any quick way, like $#array for arrays.
I can always move through the keys and increment a counter, but I'm

I may be looking at this wrong, but it seems as though the preposed solution
would work. Since the incrementing is done outside the brackets of the if
statement, the index is incremented for each element regardless of the
outcome of the if statement.
