Dual form in bibtex style file

Question

I'm writing a thesis in my language that, apart from singular and plural forms, has the dual form. I'm using bibtex and I'm having problems with translating the .bst style properly to support the dual form.

How should I modify the following code to satisfy my needs?

FUNCTION {format.editors}
{ editor empty$
    { "" }
    { editor format.names
      editor num.names$ #1 >
    { ", editors" * }
    { ", editor" * }
      if$
    }
  if$
}

Answer 1

The following seems to work:

FUNCTION {format.editors}
{ editor empty$
    { "" } 
    { editor format.names
      editor num.names$ #1 >
        { editor num.names$ #2 > { ", editors" * } { ", two editors" * } if$ }
        { ", editor" * }
      if$
    }
  if$   
}

Change "two editors" with your dual form.
