Reporting Facility Modes of Operation

This chapter discusses each of the four modes of operation, how and why specific modes are entered, and what resources are necessary when a particular mode is invoked. The four modes of operation are:

Primary
Secondary
Write-Only
Library Maintenance

Any operating mode is accessible through a single execution of the Reporting Facility. The mode of operation for any particular run is determined at runtime. The system enters a mode in one of two ways:

Explicitly, directed by your selection of a basic processing option
Implicitly, directed by the Reporting Facility after interpreting the source commands and determining the most efficient utilization of resources

After you enter any of the operating modes, the Reporting Facility is dedicated to that activity or processing method for the duration of the run.
