Dear all,

I need to check an Object-Z specification. I downloaded the Wizard checker from University of Queensland: http://www.itee.uq.edu.au/~smith/tools.html but failed to get this checker to run. Can anyone point me in the direction of another Object-Z checker or explain what is going wrong with the Wizard checker. I have tried to contact the University of Queensland group, but I have not received a reply.

Thanks,
Denis Reilly

Hi Denis,

A couple of questions first:

1) How have you marked up your Object-Z specification? Wizard accepts an older version of the Object-Z LaTeX markup, and it can act oddly if it doesn't get exactly what it expects. (Segmentation faults are a common sign of that, in my experience.)

2) What output did you get from Wizard (if any?)

and mostly out of curiousity,

3) Who did you try to contact at UQ? I believe a few of the formal methods people have left recently, so you might have been sending e-mails into the ether.

As for another Object-Z checker, unfortunately, there isn't one - yet. There's been a lot of work done recently on heavier tools, like model checkers, theorem provers, and animators, but really not much on the lighter stuff. There is work on resolving this, but don't hold your breath for any usable tools soon.

Cheers,

Geoff Kassel, UQ ITEE/SVRC/SSE PhD student

Wizard works perfectly with Linux.  If you tried to use it with another operating system, you probably need to tune your Wizard to suit your needs.  I am using Linux and I have no problems at all.  Even if you manage to get Wizard to work you need to be careful because it is very tricky.
