 Need Help??
Late as usual I see...
Here is my suggestion
```#!/usr/bin/perl
use strict;

{
local %_;
while(<DATA>){
chomp;
if(/(\d+|[A-Z])\$/){
\$_{substr(\$_,0,(length(\$_)-length(\$1)))}->{\$1} = \$_;
}
}
for(sort keys %_){
if(scalar(keys %{\$_{\$_}}) % 2 == 0){
local @_ = sort{\$a <=> \$b || ord(\$a) <=> ord(\$b)}keys %{\$_
+{\$_}};
for(my \$i = 0; \$i < scalar(@_); \$i+=2){
if( (\$_[\$i] =~ /\d\$/ && abs(\$_[\$i] - \$_[\$i+1]) == 1) |
+| (abs(ord(\$_[\$i]) - ord(\$_[\$i+1])) == 1) ){
print \$_{\$_}->{\$_[\$i]}.";".\$_{\$_}->{\$_[\$i+1]}."\n"
+ ;
print \$_{\$_}->{\$_[\$i+1]}.";".\$_{\$_}->{\$_[\$i]}."\n"
+ ;
}
}
}
}
}
__DATA__
AAA30
BBC5
SHT12H
DAL33B
BBC49
AAA31
BBC8
BBC3
DAL33A
BBC6
SHT12G
BBC50
Output
```AAA30;AAA31
AAA31;AAA30
BBC49;BBC50
BBC50;BBC49
DAL33A;DAL33B
DAL33B;DAL33A
SHT12G;SHT12H
SHT12H;SHT12G
Not exactly the OP's output but close...
Just a thought :)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

• Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
• Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
• Read Where should I post X? if you're not absolutely sure you're posting in the right place.
• Please read these before you post! —
• Posts may use any of the Perl Monks Approved HTML tags:

• You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
 For: Use: & & < < > > [ [ ] ]
