Subj:   RSX20F Support Floppys/DECtapes

     Enclosed in the Vx14-45 SWSKIT you will find two sets of RSX20F
floppys  and  a  DECtape.  The floppys/DECtape contain the following
tasks and support files:


     1.  Dd1:[5,5]DMP.TSK - A task to dump a front end file and file
         headers.

     2.  Dd1:[5,5]LBR.TSK - The library maintenance utility.

     3.  Dd1:[5,5]MAC.TSK - MACRO-11.  The PDP-11 assembler.

     4.  Dd1:[5,5]TEC.TSK - TECO-11.  Note that the buffer  in  this
         version  of TECO is very small since it must run in the GEN
         partition.  Also, due to the funny  console  device  driver
         which  likes  to  eat certain characters, Control-A must be
         typed in place of RUBOUT and Control-W  must  be  typed  in
         place  of  Control-U.   Other  than  these differences this
         version seems to follow the TECO reference card.

     5.  Dd1:[5,5]TKB.TSK - TKB-11.  The task builder utility.

     6.  Dd0:[1,1]RSXMAC.SML - The system macro library.  This  file
         contains  the  macro  definitions  for  all  RSX-11  system
         directives and File Control Service (FCS)  file  processing
         calls.  It is the default library for the assembler.

     7.  Dd0:[1,1]SYSLIB.OLB  -  The  system  library.   This   file
         contains  register  handling,  arithmetic, data conversion,
         output formatting, File  Control  Services  (FCS)  and  FCS
         command  line  processing  subroutines.   It is the default
         library for TKB.

     8.  Dd0:[1,1]EXEC.STB  -  The  Symbol  table  for  the   RSX20F
         executive.

     9.  Dd0:[1,2]QIOSYM.MSG - The QIO  error  message  file.   This
         file is a fixed record length file with the appropriate QIO
         error  message  in  the  record  that  corresponds  to  the
         absolute value of the QIO error number.  Thus, user written
         tasks can be written that read the error  message  file  to
         get  the  text  of  the  error instead of taking up address
         space with error message strings.

    10.  Ddn:[5,5]Vx1445.TXT - A text  file  to  help  identify  the
         media.

    11.  Dd0:[140,*]LP*.MAC - The source for  a  task  to  load  the
         LP20's  RAM  and  DAVFU  if the KL is down.  Note that this
         program has never worked!  The DAVFU appears to get  loaded
         but  I  have not managed to convince the RAM to load.  This
         is due in part to the perverse nature of  the  LP20  device
         driver.


     I encourage you to experiment with LPLOAD and  the  writing  of
other useful support/debugging tasks.  If you write something please
send it to me on floppy for inclusion on future RSX20F support kits.
Try to make the code as version independent as possible and document
any restrictions or dependencies inherent in  your  code.   Also,  I
would appreciate hearing of any problems you encounter so that I can
document them or possibly correct them.


                                Enjoy,
                                -Abdul-
