Well, for identifiers, yes. But SIXBIT was quite general, especially if you repurposed two of the characters to mean "end of string" and "CR+LF". The "@" was a popular choice for the former, perhaps because its encoding is 00; IIRC, "_" was popular for the latter. -- John Cowan http://www.ccil.org/~cowan cowan at ccil.org Long-short-short, long-short-short / Dactyls in dimeter, Verse form with choriambs / (Masculine rhyme): One sentence (two stanzas) / Hexasyllabically Challenges poets who / Don't have the time. --robison who's at texas dot net
