We should have told him HREF was a Macintosh type, creator or resource identifier code.... Those were 4 characters in length and there very well could be one by that name, and quite possibly much older than HTML.
I searched for a list of the codes, but found a database that needs a password. "Shareware" like that should be called keyware. I remember when shareware was a voluntary contribution for something that worked... not this locked keyware demoware stuff....
