Re^4: Change variable multiple times within a single string?

[2teez]

~ 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'=>'', );

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.....
