comment on

I havent read the rest of the thread, I only comment because of your mistake in the cb ;-), but the test you describe:

if ( defined($foo) and $foo eq '?' ) { 
    print "\$foo OK!\n"; 
}
[download]

Would be better (Lazier) written

print "\$foo OK!\n" 
   if $foo and $foo eq '?';
[download]

in my opinion anyway...

Note that since $foo must be a '?', then it cant be _any_ false value, defined being only one of three. Thus you can dispose of the defined test and replace it with simple true or false.

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.
