Two different concepts. The DOS tech refs are refering to the values to place in ah (I think, or was it al?) before making a DOS or BIOS int call. This is all pre-DLL days. Richard is referring to
the ordinal number within a DLL to reference a specific function located in the DLL. Not all functions in a dll have their names exported and sometimes the only way to get to them is by ordinal
number. This is one way that M$ creates 'value added' to their software by utilizing these undocumented calls.
