The MAP command identifies the image name and offset
    corresponding to an address. With this information, you can
    examine the image map to locate the source module and program
    section offset corresponding to an address.

    If the address is in system space, MAP searches for the specified
    address in executive images first. It then checks activated
    images in process space to search those images installed using
    the /RESIDENT qualifier of the Install utility. Finally, it
    checks all image-resident sections in system space. If the
    address is in process space, MAP searches the activated images
    for the process. On Integrity servers, the MAP command can also
    provide additional data for addresses in system space. If the
    address is determined to be in a code section of an executive
    loaded image or a resident shareable image, and if the image file
    is accessible and was linked using /TRACEBACK, the traceback data
    is used to obtain and display the module name and routine name
    information.
