I think there's some confusion here. UCSD Pascal was not the origin of Pascal P-code: the compiler that generated P-code was the 1973 Zurich P-compiler, part of the P-kit. The idea was for the user either to write an interpeter or modify the source of the P-compiler and replace its code-generaring routines. However, according to Wirth, "the reluctance of many to proceed beyond the interpretive scheme also gave rise to Pascal's classification as a 'slow language,' restricted to use in teaching." Andrew.

My personal definition is that a language is interpreted if the majority of implementations use an interpreter. And Pascal would not be among the list. Martin -- Martin Krischik |
