EBCDIC Code

• Extended Binary Coded Decimal Interchange Code
  • eb-si-dik
  • Devised in 1963 and 1964.
  • An 8 bit code
  • Based on BCD
  • Apparently IBM still uses this today on their mainframes. See This IBM page
• 
  • Start at Fx, note F0₁₆ is 0, F1₁₆ is 1 ...
  • Control codes are 0x₁₆, 1x₁₆, 2x₁₆ and 3x₁₆
• Note the characters in EBCDIC have holes in them.
  • 'i' + 1 ≠ 'j'
• Note that sorting is problematic with direct character comparisons.
  • "Dog" < "dog"
  • This is true in ASCII
  • But it is not true in EBCDIC
• There are other holes.
  • these were used for localization.
