Accessing a hash whose name is constructed I want to access some data from a hash, but want to build that hash's name on the fly... here's the code: %hello = (a => 'doggy'); print ${'hell' . lc 'O'}{a}; does the trick as does: print %{'hell' . lc 'O'}->{a}; however, under "use strict", this fails, since %hello isn't declared with "my".

Print a separator between each iteration of a foreach loop I want to print a separator between each iteration of a foreach loop, but not after the last element. How do I avoid printing the last extraneous comma in the following code snippet? foreach (@ARGV) { print $_, ','; } print "\n"; In this simple example join ',' would suffice, but the real body of the forea... 17 Apr 2008 08:33

Can "perldoc" take input from a pipe? Dear All, Is there a way to make perldoc take its input from stdin? I tried the obvious: command | perldoc but it didn't work.

I am testing, whether the two folde... 20 Apr 2008 05:00

Creating PDF documents from a Perl Program... Hi there, I'm working on a database driven website and I need to output data in PDF format. The database handling is all written in Perl so I'd prefer to stick to Perl if possible, hence my question in this newsgroup! I've done some research and come up with a couple of ideas: PDF on the Fly from Nottingham Un... 21 Apr 2008 13:19 |
