   I noticed this, perform little investigation around, than discovery the   
   "ESC(0" sequence doing this.   
   Asking ansicon author got following reply:   
      
      
   That's how it's supposed to work.  Switching to DEC special graphics replaces   
   the lower case letters   
   and some other characters with graphic characters.  This means, for instance,   
   you can switch to   
   graphics, use ASCII letters to draw a box, then switch back.

   It could be according the for /l loop performing number of iteration depend on   
   input number.
