"The most effective debugging tool is still careful thought, coupled with judiciously placed print statements."
Brian Kernighan, "Unix for Beginners" (1979)
Still true in 2015.
sub tryagain5 {
my ($messagetouser) = @_;
my $ans = callandresponse($messagetouser);
my $count=1;
# DEBUG
print "ans is <<$ans>>\n";
print "count is <<$count>>\n";
while ($count < 5 and $ans =~ /^\s*\n/) {
$count++;
$ans = callandresponse ($messagetouser);
}
if ($ans =~ /^\s*\n/) {
return 0;
}
else {
return $ans;
}
}
You should learn how to indent your programs properly: use perltidy. Bad indentation (like yours) is a serious hindrance to careful thought.

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).
