      Jon,

      Thanks for the quick response. I'll have to digest what you sent, but if I
      need more help I'll be sure and ask. That's one thing about this list --
      questions always gets answered.

      Thanks again,
      Rick.

      Could create own buffer extensions to cope with the tab width setting i.e. mysql.emf. Then in the .sql file you can introduce the header:- /* -!- sql

        Could create own buffer extensions to cope with the tab width
        setting i.e. mysql.emf. Then in the .sql file you can introduce
        the header:-

        /* -!- sql tabsize:3; -!- */

        ... SQL file ....

        This sets the tab size in the header and it is adopted for
        that buffer only. The problem with setting $tabsize is that
        it affects all buffers which is not generally desirable.
        You probably want to leave $tabwidth alone as this causes
        mis formatting errors in other editors.

        If you use the tab key then may be easier to perform
        a buffer bind of <tab> and <S-Tab> in the fhook to
        map these onto inserting 3 spaces. If you need some
        help with this then shout.

        Looking at the SQL hook file then it is very basic -
        if you are doing a lot of work in SQL then it will
        be work adding indentation and comment rules.
        (Look at hkemf.emf) for an example.

        Regards
        Jon.

        File mysql.emf
