Hello Mike Haertel,
 
I've a problem with the join-command
2 Files , compare-field  in one file first in the other second filed.
Files attached
 
I want as output to have the compare-file and then the rest-content of file_1 followed by the rest-content of file-2
Doesn't work. See Script. (also attached)
 
My mistake?
 
Kind Regards
Mit freundlichen Grüßen

Peter Kluge
