Thanks very, very much!  That's so simple!  I had tried each, but not 
together.

Does this, however, mean that compressing the module is not an option?  
If I read correctly, the "-s 4" option is only for uncompressed modules, 
and there seems to be no analog to RawCom4 that handles very large entries.

Jesus accepted you into His heart?"; not "have you given your whole
life for God", but "has God given His whole life for you"
