        RT-11 V05.04 Customization Patches - Offset Symbol Definitions
        --------------------------------------------------------------

     The RT-11 Installation Guide contains customization patches for the moni-
tors  and  the  utilities.   As  described  in the manual, the addresses to be
patched are defined as symbols, not absolute addresses.  The values of symbols
for  monitor customization patches are obtained from the link maps distributed
with RT-11 as the files RTBL.MAP, RTSJ.MAP, RTFB.MAP, and RTXM.MAP.

      The link maps for the utilities are not  distributed  however,  and  the
following symbol values should be used to apply customization patches to them.
The section number refers to the relevant section in  the  RT-11  Installation
Guide.
