Small correction: PASCAL/USAGE=64BIT_TO_DESCR does NOT change the compiler's treatment of pointers. Interpreting pointers as unsigned values has to be provided by the programmer. The qualifier only allows for P2 structures to be used as actual routine parameters via descriptor, which otherwise would be flagged as a compile time error.
