That seems reasonable, but what is the calling sequence expected by plframe? 
For instance, the C calling sequence for plscmap1 is "plscmap1(r,g,b,ncol)". 
One would then expect the tcl calling sequence to be "plscmap1 r g b ncol". 
That is not what plframe expects. I haven't analyzed exactly what it wants, but 
the first parameter is supposed to be ncol.
