I suppose that you have defined the operator MoverN by something like
\pstVerb{ /MoverN { < some code taking two numbers from the stack and leaving their binomial coefficient > } def }
The operator must then be addressed as  MoverN  (without the slash, which is needed only while defining it).  Then the print command
\psPrintValue{ 3 0 MoverN }
(without the slash) should print the binomial coefficient  "3 over 0" = 1.
