DESCRIPTION

Object identifiers can be up to 31 bits and must be unique within a program.  genobj generates unique 31-bit integer numbers.  Be cautious if you use a combination of user-defined and genobj-defined numbers to generate object numbers.  genobj will not generate a current object number. 

genobj is not required to name an object.
