We had a problem one day with print files being shipped to the NET.             
The problem was that the message you normally get,                              
         PRT FILE 1234 TO NET COPIES 001 NOHOLD                                 
                                                                                
would come out                                                                  
         PRT FILE 1234 TO NET COPIES 001 SYSHOLD, not NOHOLD.                   
                                                                                
The NET machine would then never ship the files, they would sit in              
his queue until you did a "CP CHANGE NET READER ALL NOSYS"                      
                    and a "CP SMSG   NET REORDER"                               
                                                                                
The problem started after a power surge one day, and refused to go              
away after FORCEing and restarting the NET, and also didn't go away             
after another IPL.                                                              
                                                                                
I still don't quite know what caused it, or why, but it seemed to               
go away after Mike did a "CP FREE NET" command.  But Mike didn't                
quite understand it either, because it would only happen to print               
files shipped to the NET, not punch files.
