Here's a partial solution. It doesn't "hook up" cross connections between streams yet, but notes the unresolved connections following the resolved connections.
use warnings;
use strict;
my @lines = <DATA>;
my @splitLines = map {[/('....'..[-\d]*.) -> ('?....'?..[-\d]*.)/]} @l
+ines;
my %ends;
for (@splitLines) {
next if $_->[0] !~/T(?:Dif|Dig)/;
$ends{$_->[1]} = $_->[0];
}
for (keys %ends) {
my $match = "$ends{$_}$_";
@splitLines = grep {"$_->[0]$_->[1]" ne $match} @splitLines;
}
while (@splitLines) {
my $match;
for (@splitLines) {
next if ! exists $ends{$_->[0]};
$ends{$_->[1]} = "$ends{$_->[0]} -> $_->[0]";
$match = $_;
delete $ends{$_->[0]};
@splitLines = grep {$_ ne $match} @splitLines;
last;
}
last if ! $match;
}
print "$ends{$_} -> $_\n" for sort keys %ends;
print "*** $_->[0] -> $_->[1]\n" for @splitLines;

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).

or How to display code and escape characters
are good places to start.
