Re: strings and hddm-c

["Mark M. Ito" <marki@jlab.org>]

Richard,

The version I am using is the following:

https://halldsvn.jlab.org/repos/tags/release-2008-10-21/src/programs/Utilities/hddm/hddm-c.cpp

and you checked in a better version on Jan. 7 on the trunk, better in 
the sense that it works for me.  Thanks.
