Reporting Facility Modes of Operation › Library Maintenance Mode

Library Maintenance Mode

The Library Maintenance mode provides the only means for maintaining the Reporting Facility call library. Using this library enables you to catalog frequently used statements or groups of statements for later retrieval.

You can enter Library Maintenance mode only by specifying the LIBRARY command. If you specify the LIBRARY command, it must be the first command in the input source stream.

The run stream consists of a series of specialized Library Maintenance commands. The commands and their basic functions are:

LIBRARY

Instructs the Reporting Facility to enter the Library Maintenance mode. This must be the first command in the input stream or must immediately follow the first OPTION command.

CREATE

Preformats the entire extent when used before you use any Reporting Facility call library. Perform this function only once, usually during initial installation of the Reporting Facility.

LOAD

Specifies that any source statements that follow will be cataloged in the library with a unique name. The data portion of the member to be cataloged can be terminated by another Library Maintenance command, an END command, or end-of-data on the input stream. Use this facility to add new members to the library or to update existing members.

CONDENSE

Allows the periodic reorganization of the library after considerable DELETE/LOAD activity. The Reporting Facility automatically condenses the library when less than 10 percent of the total library area remains available for use. But it never physically deletes a member from the library until after performing a CONDENSE function.

DELETE

Marks the specified member for deletion from the library. The system deletes the member when the library is condensed, but the member is inaccessible until the condense takes place. Space on the library is not available for reuse until a reorganization takes place.

DISPLAY

Allows you to display various items in the library on the system printer, or punch specific members to an alternate data set.

These data sets are required to execute in the Library Maintenance mode:
