Boot was overwhelmed by the prospect of running a DOS program so I offered to run the case for him.
As you can see from the output, the hole plates are chosen to provide all the divisions through fifty; beyond that some are possible but many require higher number hole plates which the program specifies.
Alternatively, those higher number divisions can be done by using my ROTARY program.
Turns & holes/plate for dividing head with worm gear ratio = 72:1
Available hole plates =
