     1.0  INTRODUCTION

             RT11V4.00H is RT11V4.00C  and  Fortran  V2.5  with  all  patches
     available  from DEC (patch level H).  It has been tested with MULTI V2.1
     and  requires  two  new  versions  of  the  text  files  CAMLIB.TXT  and
     LIBPRG.TXT   for   MULTI  to  work.   Because  many  users  are  working
     successfully with MULTI V2.1 and RT11V4.00B (ZG0152), we have decided to
     not  complicate  matters by making a general distribution of V4.00H that
     requires changes to MULTI.  This change would be more  natural  when  we
     distribute  RT11V5.   RT11V4.00H  is  available  on  demand to users who
     require it because of some problem with V4.00B or Fortran  V2.5  without
     patches.   You must be sure to get the new MULTI files at the same time.
     RT11V4.00H is in the computer tape vault as ZG0219 in SNPSHT format (800
     BPI  called  RT11V4).   You  should follow Bison Note 9 to copy the tape
     from the tape vault and PN164 to copy to an RK05 or RL01.



     2.0  EXCEPTIONS TO PN164

     RT11V4.00H is generated to  support  FPU  and  End  of  Month  Rollover.
     RT11V4.00B  on ZG0152 did not include this support and halted the system
     on an FPU error.  Some users prefer  to  forego  these  features  for  a
     smaller  system.  Two other systems have been generated for users who do
     not want to use the extra 26 decimal words required for FPU support  and
     47  decimal  words  for  rollover  support.   A  third  system  has been
     developed to provide the minimum support necessary to run MULTI-time-out
     support  (needed for connected machine addon-could be deleted for MULTIs
     without connected machine addon), input buffer of 80 characters  instead
     of default 134, standard output buffer of 40 characters, no FPU support,
     no rollover, no Batch support, no device drivers except DL and NL, error
     support,  and  five  extra device slots (instead of 10).  If you want to
     use this system (TINYRT.SYS),  you  should  have  two  systems  on  your
     disk-standard   RT11SJ.SYS   and   TINYRT.SYS.    The  handlers  on  the
     distribution disk should be in an order so that when the  system  starts
     installing handlers, the first 5 handlers on the disk should be the ones
     needed by MULTI.  You can invoke TINYRT.SYS by typing BOOT  TINYRT.   If
     the handlers are not in a good order on the disk, you must R RESORC with
     /A  switch  and  determine  which  handlers   are   installed.    REMOVE
     unnecessary  handlers  and  INSTALL  necessary  handlers.  After running
     MULTI, if you need the standard system back to Batch,  Boot  RT11SJ.SYS.
     The  following  chart  shows  the names of the SYS, MAP, and SYCND files
     associated with the four possible RT11 systems on the distribution disk.

     If you want either RTSJFP.NRO or RTSJNR.NFP as your  system  instead  of
     RT11SJ.SYS, you should:





     COPY/SYS RT11SJ.SYS RT11SJ.RFP          to save standard system

     REN/SYS RTSJNR.NFP RT11SJ.SYS or REN/SYS RTSJFP.NRO RT11SJ.SYS

     COPY/BOOT RT11SJ.SYS DK:


     You should also be aware of the following defaults in  RT11V4.00H:   800
     BPI  for  both  the  TU10  and  TJU16,  line  printer  set for model 800
     Versatec, and the serial line printer handler set for the CSR and vector
     used  at  Fermilab  (175610  and 310).  A new version of SNPSHT includes
     better error messages and support of the smart boot.
