SYNOPSISOPNGKS - Opens GKS, opens and activates an NCAR GCM workstation (workstation of type 1) with workstation ID of 1 and connection ID of 2.
CLSGKS - Deactivates workstation 1, closes workstation 1, and closes GKS.
PLOTIF - A line-drawing routine, described in terms of "pen moves". Most calls to PLOTIF specify whether the "pen" should be up (not drawing) or down (drawing) and then move it to a designated position in the fractional coordinate system. The polylines resulting from the pen moves are buffered; some calls to PLOTIF just cause the SPPS polyline buffer to be flushed.
FRSTPT - generates a "pen-up" move to a specified point in the user coordinate system. FRSTPT is used in conjunction with the routine VECTOR to draw lines.
VECTOR - generates a "pen-down" move to a specified point in the user coordinate system. VECTOR is used in conjunction with the routine FRSTPT to draw lines.
POINT - draws a point at a specified position in the user coordinate system.
POINTS - draws a marker at each of a series of specified positions in the user coordinate system. The markers can also be connected by drawing lines between them.
LINE - draws a line from the point (X1,Y1) to the point (X2,Y2). The "pen" (for subsequent calls to FRSTPT, VECTOR, PLOTIF, and PLOTIT) is left at (X2,Y2).
CURVE - draws the curve defined by a specified series of points in the user coordinate system. The "pen" (for subsequent calls to FRSTPT, VECTOR, PLOTIF, and PLOTIT) is left at the location of the last point in the curve.
SFLUSH - Flushes polylines, accumulated through calls to the routines PLOTIF and PLOTIT, from the SPPS polyline buffer shared by those routines; updates all open workstations; and flushes all system-level I/O buffers.
FRAME - advances to the next picture in the case of CGM output, and pauses in the window of most recent creation for X11 output. A mouse or key click in the window on pause will cause all active workstations to be cleared.
SET - defines the mapping between fractional and user coordinates: sets the values of the SPPS internal parameters 'LS' (axis linear/log scaling) and 'MI' (axis mirror imaging); defines GKS normalization transformation 1.
GETSET - returns a set of values which, if used as arguments in a call to SET, will cause normalization transformation 1, axis linear/log scaling (internal parameter 'LS'), and axis mirror imaging (internal parameter 'MI') to be defined in such a way as to duplicate the combined effects of the current normalization transformation, axis scaling, and axis mirror imaging.
SETUSV - sets the value of one of the internal parameters of SPPS.
GETUSV - gets the value of one of the internal parameters of SPPS.
CFUX, CFUY - Converts from fractional coordinates to user coordinates
CUFX, CUFY - Converts from user coordinates to fractional coordinates
