     George,
     I don't think Windows 1.04 had DLLs!  It ran in real mode and used
simple .EXE files as programs and nothing else.

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.
