AH, damn it I have forgotten everything, I swear.

Don't you have a ~/learnperl/arrays/unique.pl file? You should make several of that kind, here is what I have

$ grep -i "%seen" *pl
cygwin.mingw.path.pl:           my %seen;
pm.911928.pl:    my %seen;
pm.912276.pl:my %seen_header;
pm.912276.pl:my %seen_subheader;
set.export.path.pl:    my %seen = ();

Yes, you could refer to Tutorials/perlintro/perlfaq... http://pleac.sourceforge.net/pleac_perl/arrays.html , but I find I remember these things better when I type the code myself and refer to my files :)

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.


No such thing as a small change
