Thank you wise monk yet if I modify my sub trim to ...
55 sub trim {
56 my @out = @_;
57 if ( !defined(@_)) {return "";}
58 if ( $#out == -1 ) {return "";}
59 for(@out) {
60 #next if !($_);
61 #if (!($_)) { $_ = ""; }
62 s/^\s+//;
63 s/\s+$//;
64 s/\|//g;
65 s/\n//g;
66 s/\cM//g;
67 s/\r//g;
68 }
69 return wantarray ? @out : $out[0];
70}
... I get these messages ...
Use of uninitialized value in join or string at ./b.pl line 49
Use of uninitialized value in join or string at ./b.pl line 62
Use of uninitialized value in join or string at ./b.pl line 63
... etc
I would like to not have any extraneous output.
Any suggestion?

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.
