# SYSBPM Direct Commands

The SYSBPM direct commands described in this section can be used to directly execute SYSBPM utility functions or navigate in SYSBPM screens in online or batch mode. For additional SYSBPM direct commands that only apply to particular screens, refer to the sections where the individual SYSBPM functions are documented.

SYSBPM direct commands that refer to the BP cache or buffer pool hash table only apply to buffuffer pools of the type Natural (`TYPE=NAT`), see TYPE - Type of Buffer Pool in the BPI - Buffer Pool Initialization documentation.

The following table lists all SYSBPM direct commands (including subcommands) provided, the parameters that can be used with the commands, and the equivalent SYSBPM menu functions.

The SYSBPM direct commands listed below can be entered in the Command line of any SYSBPM screen. To execute a SYSBPM direct command from any other command prompt or in batch mode, the direct command must be preceded by the keyword SYSBPM, for example:

    SYSBPM ADD BLACKLIST

An underlined portion of a SYSBPM command represents its minimum abbreviation. Parameter values that are required by a command are represented by letters in italics.

If Current Use Count is not equal to `0` (zero) and you enter a `Y` to confirm the reinitialization of the buffer, the results of the active sessions are unpredictable and Natural can even abend.
