• 128 bits for the name
• \t before .name and .comment
• 2048 bits for the comment
• print a structure direct
• bytecode has no \0
• 4 bytes at start of .cor (1 int) -- the bytecode
• all .cor files will start 0xe183f3
• apres les 4 bytes, le name= 2048 + 1 bits
• approx size 4 bytes (1 int) - -the bytecode
• apres les 4 bytes, le comment = 512 bytes
