As a DOS programmer, that's a very significant difference.

I don't believe I ever said I was just a user.  In fact, I used to write 
DOS-based programs quite regularly to accomplish specific tasks, 
including using undocumented DOS calls to make it do things outside of 
what the "normal" DOS BIOS functions would allow.

Hands up, all those here who know what INT21 is without looking it up.

Bonus points for those who can describe INT2F and how it relates to INT21 
functions.
