Where are you looking? My manual says
  OS9 I$Open
Entry conditions
  regA= access mode
  regX= address of pathlist
Exit conditions
  regA= path #
  regX= end of pathlist +1

Likewise for
  OS9 I$Create
Entry
  regA= access mode
  regB= file attributes
  regX= address of pathlist
Exit
  regA= path #
  regX= pathlist+1
