       IFLG        (an  input  expression  of type INTEGER) is zero if a particular object is about to be drawn,
                   non-zero if it has just been drawn.

       LBNM        (an input expression of type CHARACTER) is the name of the label being drawn.

       LNNO        (an input expression of type INTEGER) is the number of the line being drawn.

       SUBROUTINE AGCHIL (IFLG,LBNM,LNNO)

       This routine is not called by the user program, but by Autograph itself, just before and just after  each
       informational-label  line is drawn. The default version does nothing. The user may supply his own version
       to change the appearance of selected lines of text.

       Note:  A user version of AGCHIL should not call any other Autograph routine.
