I am looking for information regarding the RAD-50 standard, which is apparently a character encoding standard used on old PDP-11 machines. Would anyone have the specifications of this standard? Would anyone know where to find these specifications? Please respond to adiro@taurus.bitnet or adiro@math.tau.ac.il Thank you for your efforts. Adi Rosen , Tel-Aviv

The rad50 (also known as rad-40) standard uses a 40-character character set. Character Decimal Octal (space) 0 000 A-Z 1-26 001-032 $ 27 033 . 28 034 (unused) 29 035 0-9 30-39 036-047 Depending on the application, I've seen the unused character rendered as '@', '?' or '_'. To encode a rad-50 string, pad to a multiple of 3 characters with spaces (or, in some applications, the unused character). Then take the characters 3 at a time (call them i, j, and k): val == ((i*40+j)*40+k) == ((i*050+j)*050+k) -- Peter da Silva, *NIX support guy @ Ferranti International Controls Corporation.
