ascii is organized into four blocks of 32 symbols. ( 4 * 32 = 128 ) block 1 is all control functions, none print. block 2 is punctuation, and decimal digits. (and space 0x20 ) block 3 is mostly upper case latin letters, all print block 4 is mostly lower case letters (and the rubout character, which is a hold over from teletype convention for punched paper tape character deletion ) there are 128 characters in the code 0x00 to 0x7F block 1 is all non printing codet 0x00 to 0x1F blocks 2,3,4 contain 3 * 32 = 96 characters and are mostly printing but 2 are non printing: 0x20 and 0x7F I leave the last step as an exercise for the reader. ;-) -- Paul E Condon pecon...@mesanetworks.net -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
