The MEMDB command returns a formatted display of a data block (DB) beginning at the specified memory address.

The MEMDB command is available only when Filer is invoked from the System Debugger or Coroner. For information on invoking Filer from the System Debugger or Coroner, see Running Filer from the System Debugger and Coroner.


The online help lists the display options (/P, /S, /M, /L, /H, /X) as /dispopt. You can type the options at the beginning or end of the command.

Positions to the DB. Nothing is displayed unless there is a problem.
The options used to specify the format of the DB display. For detailed information about these display options, see DB.
Attempts to format and display the segment as a DB even if the segment is not a DB.
The memory address at which to begin the DB display.
Specifies that Filer should use the most recently saved value for memadd r.
This option cannot be used unless an input value has already been defined for memaddr . For more information, see Stored Input Values.

Usage Notes

The MEMDB command is similar to the DB command. See DB.

MEMDB reports an error if the segment is not a DB. However, if you specify FORCE, Filer tries to display the memory block as a data block.

MEMDB might access obsolete copies of segments, so the displays might not be current. In addition, sometimes segments are inaccessible from the System Debugger when run against a dump. Segments that are inaccessible within the debugger are also inaccessible within Filer.
