Turbo Pascal was a true compiler with an IDE as well as a business model that allowed it to meet customer demand.
Pournelle in May 1983 reported that JRT Pascal 2.0 was "intentionally a nonportable dialect", criticized its error handling, and advised beginners with the language to "stay away from it".
[3] BYTE editors in April 1983 and January 1984 reported receiving many complaints from readers on slow delivery of JRT Pascal.
Pournelle warned, however, of its "nonstandard features" and that based on Smith's experience and "lots of letters from readers who ordered JRT Pascal and received nothing ... for months", "you must then be prepared to wait" for delivery.
Besides doing great harm to the Pascal language definition, it was a bug farm, locking up my CP/M-80 computer several times an evening.
