When I get elements via the NET I often lose the (CR) ^M 
(It seems that APPLE and UNIX OS doesn't need them but DOS does.)
I usually get them from

I easily fix the entire file by loading the file into MS DOS Edit program
and then RE-SAVE it. Edit automatically adds back in the CRs after the LFs.  

  c:> EDIT

The whole process takes less than a minute.

You can easily Check the file with the DOS 'TYPE' command. 

If the file scrolls up the screen and the each line start with sat name or a
1 or a 2 then no processing is needed. 

If however it writes over itself on the bottem line or the 1 and 2s are in
the middle of the screen then your gotta 'Edit' it.
