E. File Maintenance

Messages written on the on-line printer will be of two types:

1. If errors occur during the File Maintenance procedure, a message of the form:

   (MESSAGE) LAST CHANGE AT Namennnn PRESS START TO CONTINUE
   

   is printed, and a pause occurs to allow operator action. Each (MESSAGE) which may print is described under Section 06.04.

2. At the end of the maintenance procedure a list of all files on the new BCD master tape in order of appearance is printed on-line.

The File Maintenance routine contains references to SYSLB3, SYSLB4, SYSIN, SYSUT3 and SYSUT4. Tape movement consists of reading the two input tapes SYSLB3 and SYSIN and writing the two (or three) output tapes SYSLB4, SYSUT4, and SYSUT3. At conclusion both SYSLB3 and SYSLB4 will rewind and unload, and SYSUT's will rewind.
