Thanks. I heard that a Gofer compiler (a Haskell dialect) supports counting the Beta reductions. Hence I thought GHC/Hugs would have a similar facility. Ryan Ingram wrote:

Does GHC supports/has a command for counting total beta reductions taken by a program?

Thanks.

Yes Hugs has a option "+s" but it counts some sort of reductions not exactly the beta reductions. Thanks. -Damodar 2008/11/22 Adrian Neumann

Hugs has, afaik, a "output reduction count" option somewhere. At least it had one the last time I used it.
