NAME

       AGSETP - Allows a user program to reset the values of a group of parameters containing one
       or more elements.

SYNOPSIS

       CALL AGSETP (TPGN,FURA,LURA)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_agsetp (char *tpgn, float *fura, int lura)

DESCRIPTION

       TPGN        (an input expression of type CHARACTER) is a character string of the form
                   'k1/k2/ . . . kn.', where each of the ki's is a keyword. The keyword k1
                   specifies a group of parameters, k2 a subgroup of that group, k3 a subgroup of
                   that subgroup, etc. The whole string is the name of some group of parameters
                   the user wishes to set.

                   For example, 'AXIS.' is the name of a 92-word group of parameters describing
                   the four axes, 'AXIS/RIGHT.' is the name of a 23-word subgroup describing the
                   right Y axis,

                        'AXIS/RIGHT/INTERSECTION.'

                   is the name of a 2-word further subgroup describing the intersection of the
                   right Y axis with the bottom of the grid window, and

                        'AXIS/RIGHT/INTERSECTION/USER.'

                   is the name of a single parameter specifying the point of intersection of the
                   right Y axis with the bottom of the grid window as an X coordinate in the user
                   coordinate system.

                   Obviously, these names can sometimes become rather long.  There are various
                   ways in which they may be shortened.  First, since the fifth and following
                   characters of each keyword are ignored, they may be omitted; this would
                   shorten

                        'AXIS/RIGHT/INTERSECTION/USER.'

                   to

                        'AXIS/RIGH/INTE/USER.'

                   Even fewer characters may be used, as long as no ambiguity of interpretation
                   arises. To be completely safe, use at least the first three characters of the
                   group keyword and at least the first two characters of each subgroup keyword;
                   this would shorten the example above to 'AXI/RI/IN/US.'.  Moreover, certain
                   group and subgroup keywords may be omitted entirely; for example,
                   'AXI/RI/IN/US.' may be shortened to 'RI/IN/US.'. Keywords which may be
                   entirely omitted are enclosed in brackets in the headings in the section
                   "PARAMETERS".

                   Names may also be lengthened in various ways in order to improve their
                   readability. Blanks may be used as desired on either side of a keyword. Any
                   sequence of characters not including a slash or a period may be inserted after
                   a keyword, separated from it by at least one blank. For example, the name

                        'DASH PATTERN / CHARACTER WIDTH .'

                   is equivalent to, and considerably more meaningful than,

                        'DAS/CH.' (or even 'DASH/CHARACTER.')

       FURA        (an input array of type REAL, dimensioned LURA) contains new values for the
                   parameters in the group specified by TPGN, in the same order as they appear in
                   the group. All parameters have real values (because of a portability problem
                   which arose in implementing the routines AGSETF and AGSETR). Those which
                   represent intrinsically integral quantities have a value of the form
                   "FLOAT(n)", where "n" is the integral quantity being represented. Some
                   parameters intrinsically take on character-string values; the real quantity
                   stored as the value of such a parameter is typically an identifier allowing
                   for later retrieval of the character string from a character storage area
                   inside Autograph. The routines AGSETC and AGGETC may be used to set/get the
                   character-string values of such parameters.

       LURA        (an input expression of type INTEGER) is the length of FURA (the number of
                   real elements in it). Its value may be less than, equal to, or greater than,
                   the length of the parameter group specified by TPGN. The number of values
                   transferred from FURA is the minimum of the two (but not less than one). This
                   means that if, for example, you only wish to set the first two parameters of a
                   100-parameter group, you may do so by using LURA = 2.

C-BINDING DESCRIPTION

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

USAGE

       This routine allows you to set the current value of Autograph parameters.  For a complete
       list of parameters available in this utility, see the autograph_params man page.

EXAMPLES

       Use the ncargex command to see the following relevant example: agex06.

ACCESS

       To use AGSETP or c_agsetp, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c,
       preferably in that order.    To get smoother curves, drawn using spline interpolation,
       also load libdashsmth.o.  Or, you can use the ncargf77 command to compile your program and
       load the above libraries, then, to get smoother curves, use the -dashsmth option.

MESSAGES

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