printf directly supports printing characters, decimal, and hexadecimal, so that's easy. Converting between ASCII and EBCDIC is also easy and highly efficient if you use two conversion tables:
c Syntax (Toggle Plain Text) 
  1. unsigned char ascii[] = {
  2.   /* All characters in ASCII */
  3. };
  4.  
  5. unsigned char ebcdic[] = {
  6.   /* All characters in EBCDIC */
  7. };
  8.  
  9. unsigned char to_ascii ( unsigned char c )
  10. {
  11.   return ascii[c];
  12. }
  13.  
  14. unsigned char to_ebcdic ( unsigned char c )
  15. {
  16.   return ebcdic[c];
  17. }
I'm here to prove you wrong.
