I am writing Postscript programs that contain nothing but boxes. A sample program which draws only a single box is attached below. A real program would simply contain a very large number of "x1 y1 x2 y2 Box" statements. 

My problem is that if the program contains too many boxes (somewhere over 10,000), Illustrator and Ghostview cannot display the file. Ghostview gives an error message that looks like an execution stack overflow to me. How can I fix this? 

The problem is not in the sheer number of boxes being drawn. If I use a for loop, I can draw the same number of boxes or more with no problem. The problem is that somehow my Box command is not being immediately executed. Using the exec command did not help. 

I'd love to hear from an expert on this. 

Thanks,
