       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.

       KDSH        (an input expression of type INTEGER) is the value of AGCURV's last argument, as follows:

       SUBROUTINE AGCHCU (IFLG,KDSH)

       This routine is not called by the user program, but by Autograph itself, just before and just after  each
       curve  is  drawn.  The  default  version  does nothing. The user may supply his own version to change the
       color, intensity, line style, etc. of selected curves.

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