coding of primitives ( wizard stuff )
[numptr] = funptr(name)
a string, the name of a primitive
the internal routine number of the primitive
Utility function (for experts only) to get the internal routine number numptr
of the primitive 'name'. numptr is formed from the interface
number fun and the routine number fin of the primitive in its interface
by numptr = 1000*fun + fin (fin < 1000). From numptr you can get
the interface number fun = floor(numptr/1000) which may be useful to link a
dynamical interface with arguments passed by reference (see example section).
