title: convert user input character by character with batch
body: <p>ok basicly i want a simple batch program to change X characters to Y characters in a way like this</p>
  
  <pre><code>a-b
  b-c
  c-d
  d-e
  e-f
  etc etc etc
  </code></pre>
  
  <p>ive looks up strings and other variable tricks but it doesnt work. heres what i tried and you can see on "codeb" where i tried an alternate method</p>
  
  <pre><code>set /p code=[paste your code here]
  set code=%codea:~1%
  set /a %code:~2% %codeb%
  </code></pre>
  
  <p>this was basically my way of attempting to split all the input characters into seperate variables.</p>
  
  <p>if your feeling....bored below is the exact conversion for the translation</p>
  
  <pre><code>a='
  b=v
  c=x
  d=s
  e=w
  f=d
  g=f
  h=g
  i=u
  j=h
  k=j
  l=k
  m=n
  n=b
  o=i
  p=o
  q=\
  r=e
  s=a
  t=r
  u=y
  v=c
  w=q
  x=z
  y=t
  z=/
  </code></pre>
  
  <p>essentially i should be able to "paste" this "v'rxg" into the batch and hit enter and it then displays "batch"</p>
