After the first experimental code had been written in #UCSD_Pascal, the majority of #Lisa_OS was written in #Lisa_Pascal. The first versions of #Mac_OS and applications for Lisa OS were written in #Clascal, an early version of #Object_Pascal. The coevolution of #Pascal and Apple OSes is interesting.
