NAME

       CPCHIL - Called by Conpack routines as the informational label is drawn.  The default version does
       nothing.  A user-written version may be supplied to provide control as the label is drawn.

SYNOPSIS

       CALL CPCHIL (IFLG)

DESCRIPTION

       IFLG        (INTEGER,  input)  is  positive  if an action is about to be taken, negative if an action has
                   just been completed.  The action in question is defined by the absolute  value  of  IFLG,  as
                   follows:

                   •   The  value  1  implies  the determination of the size of the label (by means of a call to
                       PLCHHQ, in the package Plotchar, with ANGD=360.).

                   •   The value 2 implies the filling of the box around the label, which  is  done  before  the
                       drawing of the label itself.

                   •   The  value  3  implies  the  drawing  of  the label (by means of a call to PLCHHQ, in the
                       package Plotchar).

                   •   The value 4 implies the drawing of the box around the label,  which  is  done  after  the
                       drawing of the label itself.

USAGE

       The  routine  CPCHIL  is not to be called by the user. It is called several times by CPLBAM and/or CPLBDR
       while the informational label is positioned and drawn. The default version  of  CPCHIL  does  nothing.  A
       user-supplied replacement may change attributes such as color and line width (by calling the SPPS routine
       SETUSV  or  the  appropriate  GKS  routines).  The text of the label may be retrieved by means of a "CALL
       CPGETC ('CTM',CVAL)". The text of the label may be changed by means of a "CALL CPSETC ('CTM',CVAL)"; this
       should only be done during a call with IFLG = 1 or IFLG = 3, and, if it is done for one of those  values,
       it should be done for the other.

ACCESS

       To use CPCHIL, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
