I have added code to EDITR to trap the case of one source from a 
multi-source file.  The low level data read routines return the data as 
if there were only one source and the source name and number were lost.
The name that appeared on the editing displays was the name of source 
one not the current one being edited.  The MNJ will fix things tomorrow.
