RE: Number of objects in a library

[Kurt Goolsbee <K.goolsbee@xxxxxxxxxxxxx>]

Thanks for the code.  It compiles but it won't run.  Our machines are @
level 40 & 50.  Here is what I get.

 Statement/Instruction . . . . . . . . . :   /0002      
 Program . . . . . . . . . . . . . . . . :   LIBSIZE    
 Recursion level . . . . . . . . . . . . :   1          
                                                        
Object domain or hardware storage protection violation. 

I'll try the same logic in a C program using QusMaterializeContext.  Thanks
Doug for the RPG example but I no habla RPG.
