NAME

       PCGETR - Retrieves the real value of an internal parameter of type REAL or INTEGER.

SYNOPSIS

       CALL PCGETR (PNAM,RVAL)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_pcgetr (char *pnam, float *rval)

DESCRIPTION

       PNAM        (an input expression of type CHARACTER) specifies the name of the parameter to
                   get. The name must appear as the first two characters of the string. If the
                   internal parameter is one of the two (´BC´ and ´CC´) that are arrays, the
                   index of the desired array element may appear, enclosed in parentheses, in
                   columns 3 and following. Other characters may be used to document the use of
                   the parameter being retrieved; for example, instead of just ´MA´, one can use
                   ´MA - MAPPING FLAG´ and, instead of ´CC(10)´, one can use ´CC(10) - SPECIAL
                   COLOR 10´.

       RVAL        (an output variable of type REAL) is the name of the variable into which the
                   value of the internal parameter specified by PNAM is to be retrieved.  If the
                   internal parameter is a value "r" of type REAL, the value returned is "r".  If
                   the internal parameter is a value "i" of type INTEGER, the value returned is
                   "REAL(i)".

C-BINDING DESCRIPTION

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

USAGE

       This routine allows you to retrieve the current value of Plotchar parameters.  For a
       complete list of parameters available in this utility, see the plotchar_params man page.

EXAMPLES

       Use the ncargex command to see the following relevant examples: cpexcc, epltch, vvexcc,
       fpchiqu.

ACCESS

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

MESSAGES

       See the plotchar man page for a description of all Plotchar error messages and/or
       informational messages.
