Jerry, 

Thanks for the report.  

I succeed running "exec spwho myusername" with:

* last night's FreeTDS snapshot
* DBD::Sybase 0.95
* SQL Server 2000
* TDS version 7.0
* i386 NetBSD

but fail if "sp_who" returns an error message instead of a result set (ask
for an invalid login).  

This might have to do with our recent changes to handle output parameters,
or to our earlier mishandling of queries that produce no result sets.  I
can't test further right now.  

Here's the bt:
