The SGB (Staf-GC-STAR/BaBar) code works! Congratulations to Jeff & Torre! The proof is /grandch/u/GCA/olson/stafgca/itworks.kumac which is a copy of the last.kumac. For Jeff's info, the final trick was to build it with the SL98i version of the library. This fixed the seg. violation between the return of CreateEvRead and kuip command line. Tomorrow after I get back to Berkeley I'll try it with the SCA code. Doug
