Hello everyone,

I am using latest version of SPIN v6.4.7. I am working on the exercises on the webpage of SPIN:

http://spinroot.com/spin/Man/1_Exercises.html

In exercise 1(i), when I run the following command in steps:

$ spin -DN=24 -m -search -DMEMLIM=17 -w15 ex_1f.pml

I don't get any output related to the number of states and memory. Instead I have some digraph output (Please see attached file). How do I get the number of states?

Please note that: I have to run the above command in steps since -search results in an error:

"'pan' is not recognized as an internal or external command, operable program or batch file." Nevertheless, the 3 step procedure has worked fine so far in every exercise. So I don't think it is the problem.

I hope someone can help. Thanks.
