367:, a Macintosh-variant of the Green Hills C compiler designed specially for Apple and which was similar to the version that was available for the Lisa Workshop. In addition, the original MPW C compiler was known for its casual and frequently humorous error messages ("we already did this function"), as well as occasionally addressing users by name. These quirks were not carried on after the PowerPC transition, when Apple replaced the originals with compilers written by Symantec. Pascal support was no longer provided by the mid-90s due to declining popularity of the language. MPW was always targeted to a professional audience and was seldom used by hobbyist developers due to the considerable price for the package; by the time it was made freeware it had long since been superseded by offerings from Symantec and

MPW was started in late 1985 by Rick Meyers, Jeff
Parrish, and Dan Smith (now Dan Keller). It was going to be called the Macintosh Programmer's System, or MPS. (Notice that coincidentally the three last names start with MPS.) 'MPS ' has always been the
