So, if you have come across a compiler providing a memory model different than the above mentioned three cases, please post a reply to let me know which compiler/target and the bit widths for CARDINAL and LONGINT.
Note that LONGINT was not introduced until the 3rd Edition of PIM so it was not implemented in early compilers e.g. Volition Systems.
