Dear Drew Krause,

To Joe Fields' answer to your question about `ConstantWeightSubcode'
I would like to add the following:

On a Dos machine the external binaries used by this function
are simply not available. Therefore calling `ConstantWeightSubcode'
will not work, and a global Guava variable is set to false.
This subsequently causes an error.

Currently we are working on a GAP4 version of Guava, and we will
see how to make the error messages more informative in these
cases.

Best wishes,
