| vax_primitives 
 | 
             vax_primitives, file  
 
     sets FILE primitive data types to be native to VAXen, H-double, only.  
interpreted function, defined at i0/std.i   line 2043

| vaxg_primitives 
 | 
             vaxg_primitives, file  
 
     sets FILE primitive data types to be native to VAXen, G-double, only.  
interpreted function, defined at i0/std.i   line 2051

| viewport 
 | 
             port= viewport();  
 
     returns [xmin,xmax,ymin,ymax] of the current viewport (or 0,0,0,0  
     if currently plotting to system 0) in NDC coordinates.  
builtin function, documented at i0/graph.i   line 1370

| volume 
 | 
             volume(r, z)  
 
     returns the zonal volumes of the 2-D cylindrical mesh (R, Z).  
     If R and Z are imax-by-jmax, the result is (imax-1)-by-(jmax-1).  
     The volume is positive when, say, Z increases with i and R increases  
     with j.  For example, volume([[0,0],[1,1]],[[0,1],[0,1]]) is +pi.
