NAME

6       CPCHCF - Called by Conpack routines when a constant field is detected.
7       The default version does nothing.  A user-written version may be
8       supplied to provide control as the constant-field message is drawn.

SYNOPSIS

11       CALL CPCHCF (IFLG)
12

DESCRIPTION

14       IFLG        (INTEGER, input) is positive if an action is about to be
15                   taken, negative if an action has just been completed.  The
16                   action in question is defined by the absolute value of
17                   IFLG, as follows:
18
19                   ·   The value 1 implies the determination of the size of
20                       the label (by means of a call to PLCHHQ, in the package
21                       Plotchar, with ANGD=360.).
22
23                   ·   The value 2 implies the filling of the box around the
24                       label, which is done before the drawing of the label
25                       itself.
26
27                   ·   The value 3 implies the drawing of the label (by means
28                       of a call to PLCHHQ, in the package Plotchar).
29
30                   ·   The value 4 implies the drawing of the box around the
31                       label, which is done after the drawing of the label
32                       itself.
33

USAGE

35       The routine CPCHCF is not to be called by the user. It is called
36       several times by Conpack while a constant-field label is being drawn.
37       The default version of CPCHCF does nothing. A user-supplied replacement
38       may change attributes such as color and line width (by calling the SPPS
39       routine SETUSV or the appropriate GKS routines). The text of the label
40       being written may be retrieved by means of a "CALL CPGETC
41       ('CTM',CVAL)". The text of the label may be changed by means of a "CALL
42       CPSETC ('CTM',CVAL)"; this should only be done during a call with IFLG
43       = 1 or 3 and, if it is done for one of those two values, it should also
44       be done for the other. When CPCHCF is called, the parameter 'ZDV' will
45       have been set to the value of the field; its value may be retrieved and
46       used by CPCHCF.
47

ACCESS

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