Hi Eric,

      Thanks a lot for this -- vlbampcl works.  Another quick question: how
do I delete a version of a table?  I by mistake ran vlbampcl with the wrong
settings, and want to delete the resultant SN and CL tables so later tasks
don't use it if / when I forget to set the correct values for "gainuse",
etc.  Hope all is as well as can be and stays that way -- Yosi
