As any program, System Builder v.1.01 has some restrictions. Here they are.

Maximum number of properties   40
Maximum number of methods      40
Maximum number of object types 20
Maximum number of objects      30
Maximum number of images       30
Maximum method length         255 symbols
Maximum total program length  400 lines
Maximum nested methods calls   16
Maximum number of If          128

I hope, they will not disturb you. I promise to recompile program for other values you need, if it will be possible (for example, maximum method length is limited by Pascal string type, and it's not so easy to increase it).
