NAME

       GETSI - returns the exponents which define the plotting range in the plotter address unit
       coordinate system.

STATUS

       Plotter Address Units (PAUs) are no longer used in NCAR Graphics; thus, GETSI is
       considered an obsolete routine.

       The current recognized coordinate systems are GKS world coordinates, GKS normalized device
       coordinates, NCAR Graphics fractional coordinates, and NCAR Graphics user coordinates.
       See the NCAR Graphics document "The Use of X/Y Coordinates in NCAR Graphics" for a
       description of these coordinate systems.

       GETSI continues to be provided for compatibility of early NCAR Graphics codes.

       The following definition of the PAU Coordinate System is included for the purpose of
       interpreting and converting PAU codes:

       The plotter coordinates of a point are integers IPX and IPY, where IPX is between 1 and
       2**MX and IPY is between 1 and 2**MY.  MX and MY are internal parameters of SPPS; each has
       the default value 10.  Values of MX and MY can be set by routine SETI and retrieved by
       routine GETSI.

SYNOPSIS

       CALL GETSI (IX,IY)

DESCRIPTION

       IX          (an output variable of type INTEGER) is the X axis exponent for plotter
                   coordinates defining a range of 1 to 2**IX - 1.  IX has a default value of 10.

       IY          (an output variable of type INTEGER) is the Y axis exponent for plotter
                   coordinates defining a range of 1 to 2**IY - 1.  IY has a default value of 10.

ACCESS

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