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.
