 Syntax

        Set Key nn To GT_HelpRequest

 Arguments:


 Returns:

      NIL

 Description:

      This is a simple 'Help Engine'. It must be simple since I wrote it
      <g>. The routine will create the help database automatically if
      the file 'HELPFILE', is missing. If the user requests help at any
      point where it has not been previously defined, then it will create
      a blank entry in the database, with the relevant calling points &
      variables.
      It also creates and index called
      'HelpFil1.NTX' as well.The structure is as follows :-

      VARIABLE_   Character   12
      ROUTINE_    Character   12
      HELPTEXT_   Memo
      TITLE_      Character   15

      The file should be indexed on Upper(Variable_)+Upper(Routine_)

      NB This routine uses the following routines :-
      GT_ELEVBAR      by       MartDude
      GT_OPEN         by       MortDude
      GT_BLOCK        by       Me!
