It is no joke, I saw the article over ten years ago. Since posting my original message, I have found a reference to it, it did not appear in Byte magazine, but Dr Dobbs Journal instead! Both magazine publish source code, so I got them mixed up. The article I was thinking of was written by Edward Mitchell, and appeared in the January, March, May, and July 1983 issues. The titles were: Augusta -- an Ada Subset for Micros, Jan. 1983 Augusta -- 2, the Augusta P-Code Interpreter, Mar. 1983 Augusta -- Part III, Recursive Descent Compilers, May 1983 Augusta -- Part IV, the Augusta Compiler (continued), July 1983 One of the references in the Augusta articles did appear in Byte magazine, and was about a Pascal compiler written in BASIC Chung Kin-Man and Yuen H (1978): A "Tiny" Pascal Compiler, Byte Magazine, Volume 3, Numbers 9, 10, 11, September, October, November 1978. Now all I have to do is find these article someplace! --EE In article <8dbqi1$ej9$1@wanadoo.fr>, "Pascal Obry"
