BCPL it seems was originally implemented on machines that were linerly word addressable, versus the liner byte addessability of the 68000. SO if you use BCPL on a byte addressable machine, you've got to set up the compiler to produce a model of a word addressable machine in order for BCPL code to work. It'd be transparent from your BCPL environment but not from C or any other more flexable language (C not being tied to a particular memory organization). Had it been written in C you wouldn't have any of this BPTR stuff to worry about… -Dave
