in thread A Semi-automatic word search solver
Thanks for the subroutine, I think I will use that as part of the update I'm planning. As for using a prototype on the subroutine, I've always done it that way, but if this is considered incorrect or foolish, please do tell me.

Prototypes in Perl are very special. They are not --as many people expect-- a tool to check at compile-time or even run-time wether the parameters of your subroutine call are correct. Have a look at Gratuitous use of Perl Prototypes, it explains clearly why Perl "prototypes" are totally different from (for example) C "prototypes".

Thanks, that does clear it up for me, coming from a C(++) background prototyping had just become a default behaviour like putting #!/usr/bin/perl at the top of every bit of perl code has.
