NAME
       FL2INT - converts X and Y coordinates from the User Coordinate System to the Metacode Coordinate System.


STATUS
       Metacode units are no longer used in NCAR Graphics; thus, FL2INT 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
       "NCAR Graphics Fundamentals, UNIX Version" for a description of these coordinate systems.

       FL2INT continues to be provided for compatibility of early NCAR Graphics codes.  If you are writing new
       code, we suggest that you use user coordinates and fractional coordinates.  The routines CUFX and CUFY
       will convert from user coordinates to fractional coordinates.  CFUX and CFUY will convert fractional
       coordinates to user coordinates.

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

       The metacode coordinates of a point are integers IMX and IMY between 0 and 32767 inclusive.  The area
       addressed is a square in a "metacode space" that is usually mapped into a square subset of the
       addressable area of the plotting device.  Metacode coordinates were used in calls to the routine PLOTIT
       and are returned in calls to FL2INT.


SYNOPSIS
       CALL FL2INT (PX,PY,IX,IY)


DESCRIPTION
       PX          (an input expression of type REAL) is the X coordinate of a point in user coordinates.

       PY          (an input expression of type REAL) is the Y coordinate of a point in user coordinates.

       IX          (an output variable of type INTEGER) is the X coordinate of the point in metacode
                   coordinates.

       IY          (an output variable of type INTEGER) is the Y coordinate of the point in metacode
                   coordinates.


ACCESS
       To use FL2INT, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
