CX:DX -> array of FAR pointers to entry points (see #03877)

Note: Most functions are invoked by pushing the DWORD parameter block pointer and then performing a FAR call via the appropriate vector of the entry point array, placing the FAR address of the function's parameter block on the top of the stack
