The New Day procedure uses the program list in member PROGDAYM. User Daily jobs use the program list in member PROGUSR.

The New Day procedure uses Date Control record DATEREC (which contains the last Active Jobs file format date in columns 60 through 65). User Daily jobs use Date Control record DATERECU (which contains blanks in columns 60 through 65). Using the wrong Date Control record causes message CTM916W to be generated.

User Daily jobs can be run manually (that is, not initiated by the Control‑M monitor.) However, the Control‑M monitor must initiate the New Day procedure. If an attempt is made to run the New Day procedure manually, problems may be caused by failure of the Control‑M monitor to free the Active Jobs file for use by the New Day procedure.
