~ Printing the variable in each line is only showing the current value..

That is excatly my point. Since, what to print when '1' is seen is not known, I think is better to leave it out.
Your output: 

A (yes)
1 (yes)  #?
1 (yes)  #?
1 (yes)  #?
B (no)
1 (no)   #?
1 (no)   #?
1 (no)   #?
A (yes)
1 (yes)  #?
1 (yes)  #?
1 (yes)  #?
B (no)
1 (no)   #?
1 (no)   #?
1 (no)   #?

Output with a little modification: 
A (yes)
B (no)
A (yes)
B (no)

OR one can provide for '1' in hash like so: 
my %decision = ( A => 'yes', B=> 'no', '1'=>'', );

[download]
Then the output shows: 
A (yes)
1 ()
1 ()
1 ()
B (no)
1 ()
1 ()
1 ()
A (yes)
1 ()
1 ()
1 ()
B (no)
1 ()
1 ()
1 ()

Just saying.....

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
