PRODUCT MODULE SPR
EDIT NAME & EDIT QAR (WHO, DATE) DESCRIPTION
====== =========== ===== =======================
53 RMSOSM HOT RMSTACK incorrectly signed as local variable,
causing RMS to write to sharable page.
54 RMSSPT(24) 20-17022
(RLUSK, 24-Dec-81) COMPRESS not updating
DUPLICATES flag in record descriptor after
compressing bucket.
55 RMSERR(16) 20-16698
(RLUSK, 30-Dec-81) REMOVRECORD using
SDATABKT to search for record which may
not be in bucket specified; use POSRFA
instead to find bucket and record.
56 RMSASC(8) SWE (MBROWN)
(DAW, 12-Jan-81) In an LSA file, a word
of nulls is allowed before the LSN if the
LSN would be in a separate TOPS-10 buffer
than the following TAB. Instead of giving
error while reading, just skip the word.
57 RMSUPD(6) 20-17231
(RLUSK, 28-Jan-82) In updating an indexed
file when duplicates are not allowed,
DOUPDIDX calls FOLLOWPATH, allocating a
buffer, and never freeing that buffer.
This can eventually cause overflow of the
user count in the buffer descriptor and
yields a RMSBNA error, "Buffer not
allocated". Cure by releasing the bucket
after checking for duplicates.
60 RMSDSP(3) SWE (MBROWN)
(DAW, 1-Feb-82) Preserve user's registers
3 and 4, return STS in register 2.
61 RMSOPN(21) 20-17312
(RLUSK, 24-Feb-82) Repeated $OPENs on
a locked file can use up memory,
because space for an FST is allocated
and never freed.
62 RMSIDX(14) 20-17341
(RLUSK, 28-May-82) When doing a search,
a SIXBIT key "ABC" will be lexicographically
less than " BC", because a signed
comparison is done, so the first key appears
negative and the other positive. This is
causing all sorts of havoc. Use an unsigned
comparison in SINDEXBKT.
63 UTLUSE(1) 20-17546
(MBOUCHER, 2-Jun-82) RMSUTL fails with "?RMSOSE
JSYS 56 Failed" error when executing the RMSUTL
command "SET INDEX n BUCKET x" when the bucket
at page x is the root of index n.
64 RMSOSB(2) 10-32354
(RLUSK, 4-Jun-82) TOPS-10 code in PAGOUT
incorrectly calculates size of block for
output, giving positive value in left half
of IOWD. This gives an address check and
illegal address in UUO message.
65 RMSASC(9) None
(RLUSK, 14-Apr-83) Edit 56 does not
correctly handle a word of nulls
occurring in a Line-Sequenced ASCII
file. It does not allow for a word of
nulls preceding a pagemark, nor does
it correctly handle a null word before
an LSN; rather than bump the pointer
by one word (as should be expected in
most cases) it gratuitously reads in a
new buffer, disposing of up to 3
blocks of data in a single stroke.
The routine logic is so flawed, then,
that it was rewritten.
66 RMSEVC(1) None
RMSDSP(4) (RL, 19-Apr-83) With the release of
LINK v5.1, the /START switch no longer
accepts a value whose left half is the
length of the entry vector and whose
right half is the address of the entry
vector. Definition of an entry vector
must, therefore, be by a MACRO-written
REL block. RMSEVC has been written to
generate the entry vector entry for
RMS; the entry vector entry is not
desired for RMS.REL, for that would
overwrite the user's start address.

PRODUCT MODULE SPR
EDIT NAME & EDIT QAR (WHO, DATE) DESCRIPTION
====== =========== ===== =======================
300 RMSLIB(300) XXXXX (DAW,19-Jan-82) Fixup sources so DBUG=1
RMSFIL(300) will compile with no errors.
RMSOSB(300)
RMSDSI(300)
RMSDMP(300)
RMSFNX(300)
301 *ALL* XXXXX Support extended addressing.
302 RMSTAB(300) XXXXX Support new DEC standard for stream files:
ESC and CTRL/Z are no longer break characters.
303 RMSFND(300) XXXXX Fix Get for Relative files to advance NRP
pointer properly.
400 *ALL* XXXXX (RL,22-Apr-83) Clean up BLISS code.
401 RMSRSU(401) XXXXX (RL,1-May-83) Fix CBD initialization
402 RMSERR(1) XXXXX (RL,6-May-83) Stop printing messages to
RMSOSM(401) the terminal when an error occurs, especially
RMSSYM.MTB(1) the quota exceeded error from OKCREATE. Add
a new error code, ER$EXT (RMS$_EXT), File
extend error; return the JSYS error in the
STV field.
403 RMSASC,RMSFND, (AWN,Apr-83) Add RFA $GETs to stream/LSA files,
RMSOPN,RMSRSU fix LPT: output, add write-before-advancing,
write-after-advancing options.
404 RMSCNC(401) (RL,10-May-83) Add COBOTS SMU support: when
RMSDSI(401) SMU is set, do no locking and return number
RMSFND(1) of page containing record on relative $FIND.
RMSOPN(3)
405 RMSFNX (RL,11-May-83) Fix typo in FBYKEY; extra dot
in XCOPY macro call.
406 RMSLIB,RMSEXT,RMSREQ (RL,12-May-83) Remove external declarations
from RMSLIB, and put them in RMSEXT.R36.
Change RMSREQ to declare RMSEXT as a library.
407 RMSLIB,RMSUPD,RMSMSC (RL,24-May-83) Make CKEYUU use global pointers
when comparing things in the RMS section with
things in a user section. Make DOUPDIDX pass
a global address to CKEYUU if one is not given,
and make UPDUDR and UPDSQR use an XBLT for
copying things in nonzero sections. Finally,
put new macros into RMSLIB to support all
these good things.
410 RMSERR (RL,1-Jun-83) REMOVRECORD (in RMSERR) calls
DELUDR (in RMSUDR) with 3 arguments, when
DELUDR only takes 2. Thus, DELUDR never
quite gets hold of the correct record to
delete.
411 RMSDSI,RMSERR,RMSLIB, (AWN,6-Jun-83) Implement non-display keys
RMSMSC,RMSSYM,RMSTAB, PAC,IN4,IN8,FL1,FL2,GFL,AS8,UN4
RMSM2
412 RMSIDX (RL,20-Jun-83) An error in parameter binding
in GTNBKT caused a bucket to be locked when
it was not supposed to be locked.
413 RMSMSC (RL,23-Jun-83) Because byte-pointers were not
cleared before their fields were initialized
(in CKEYUU), the cruft left behind caused
equal keys to appear unequal, causing problems
on $UPDATEs.
414 RMSOPN (RL,24-Jun-83) Missing parentheses in IF
statement caused section of code to be
"optimized" out of DOOPEN.
415 RMSSDR (RL,5-Jul-83) Call to MOVEKEY from PUTSIDR
did not pass 30-bit address when needed.
Thus, the user's secondary key was ignored.
416 RMSGET,RMSPUT,RMSUPD (RL,7-Jul-83) Calls to MOVERECORD from
GETREC and UPDSQR did not pass 30-bit address
when it was needed. PUTREC needed some
cleanup around the MOVERECORD call.
417 RMSFIL (RL,8-Jul-83) A PMAP in PAGIN fails because
the caller, DOKEYBLOCKS, has incorrectly
set up the global destination page, zB.,
passing 2,,666 rather than 0,,2666. Fix
the page calculation expressions to shift
the section number down where it belongs.
420 RMSFND (RL,8-Jul-83) Make user's key buffer address
global before trying to fetch from it, in
FINDREL.
421 RMSUPD (RL,20-Jul-83) Allow changing the record
size on $UPDATE, when the record is
variable-length in a relative file, and
the new length is less than the maximum
record size.
422 RMSUPD (RL,25-Jul-83) In DOUPDIDX, when RMS checks
for duplicates on a key that has changed,
the MOVEBKTDESC macro is called with a
fetched value as an argument; it treats
this dotted name as a regular name, which
makes a dotted structure reference in the
macro cause an illegal read. BIND the
fetched value to a name, and pass that
name instead.
423 UTL??? (RL,26-Jul-83) All UTL??? modules cleaned
up and compiling/assembling normally.
Module UTLEXT has been created to contain
all external references.
424 RMSEVC (AN,20-Sep-83) Move spare copyright to loseg.
It is only needed for the REL file.
425 RMSLIB (RL,27-Sep-83) CKEYUU is unwittingly zeroing
a non-preserved register used by DOUPDIDX.
CSTRINGLE_EA uses AC12 without explicitly
naming it (by using a DMOVEM) and BLISS
assumes the AC is safe. Explicitly zero
AC7 and AC12 when safe to do so.
426 RMSLIB (RL,28-Sep-83) Make TRACE and RMSENTRY use
conditional compilation (under DBUG) to
avoid checking the debugging flags when not
needed.
427 RMSDSI (AN,5-Oct-83) SETKDB should not touch the KSDs
as they are mapped R/O to the file.
430 UTLACT (RL, 10-Oct-83) Open sequential and relative
UTLCMD files with RMSUTL; disallow use of FIX,
UTLENV UNCLUTTER and VERIFY commands with sequential
UTLIO and relative files; get the file prologue
UTLMSC correctly in BK$PROL; undefine some conversion
UTLTOP tables which are now in RMSM2.MAC; and fix
UTLUSE a memory manager bug.
431 UTLCMD (RL, 13-Oct-83) Check that file is open
UTLSYM for commands which need open file, and
set up record-to-use clause tables based
on file organization.
432 UTLCMD (RL, 19-Oct-83) Make changes to allow
UTLENV DEFINE command for relative and sequential
UTLSYM files. Also, fix the initialization code
UTLUSE for non-indexed files.
433 UTLCMD (AN, 31-Oct-83) Add new datatypes to RMSUTL
UTLACT
UTLENV
RMSFLO
RMSCNV
434 UTLCMD (RL, 31-Oct-83) Fix seq/rel files in RMSUTL
UTLACT (AN installed)
UTLUSE
UTLTOP
435 UTLCMD (1-Nov-83) Fix RMSUTL error messages
UTLTOP and report file default
436 UTLCMD (4-Nov-83) Data-type check off-by-one
437 UTLMSC (2-Dec-83) Initialize un-inited register
flagged by new BLISS compiler.
440 UTLTOP (2-DEC-83) Fix more RMSUTL error messages.
441 RMSASC,RMSEXT (8-Dec-83) The MOVST in GETASCII will insert
nulls into a record if the record has leading
nulls and crosses a page boundary.
442 RMSUDR (13-Dec-83) CHKDUP was erroneously marking
records inserted before a deleted record as
duplicate records. This corrupted the index.
443 RMSQUE (13-Dec-83) FILEQ was not creating separate
queue request blocks for UPD and DEL access.
444 RMSOPN (20-Dec-83) Because RMS always opens files
thawed, it is impossible to type or otherwise
non-RMS open a file which RMS is only reading.
Open the file Read-Unrestricted (OF%RDU) if
RMS is only reading.
445 RMSASC (20-Dec-83) After an RTB error, the code from
edit 441 reads to EOF, rather than just to the
end of record. Check MOVEFLAG when checking
buffer space left.
446 RMSINI (21-Dec-83) Currently, RMSINI maps UDDT.EXE in
whenever it maps XRMS into a non-zero section.
Instead, map DDT in only when DDT exists
in the user's section already.
447 RMSINI (21-Dec-83) Define RMSSEC (in RMSINI) to be
a global and allow the user to change it
to specify that RMS is to be loaded into
a specific non-zero section, rather than the
first free section.
450 RMSDSP,RMSGLB (RL,13-Jan-84) PA1050 keeps trapping RMS's page
creations. Turn off the non-existent page
interrupt channel with a DIC% when entering
RMS, and restore the original status when
leaving RMS. NOTE: Allow the user program
to disable this feature with the $NOMESSAGE
JSYS, which does nothing now.
451 RMSGLB,RMSFSM (RL,18-Jan-84) COBOL SMU requires COBOL to
RMSINI,RMS2X2.LNK perform two $CONNECTs on each file, which
doubles the buffer space used by each file.
XRMS at 600000 does not have enough free
memory to allow COBOL to open 8 files,
much less the ANSI maximum 16 files. Ergo,
make RMS2X2.LNK from RMS2S2.LNK and load
XRMS.EXE at 400000. Then, increase the
page table size in RMSGLB to cover the added
space. Finally, remove the crock code in
RMSFSM which caused RMS to call FUNCT. when
RMS was loaded below 600000.
452 RMSUSR (RL,24-Jan-84) Add ELS parameter to $RAB macros.
453 RMSOSB (RL,24-Jan-84) If SIN or SOUT wins a "Quota
exceeded" or "Disk full" error, make IOERROR
return ER$EXT.
454 UTLVFY Q345004 (RL,30-Jan-84) If a file contains a data
bucket in which all entries are deleted,
a VERIFY (with file opened for output) or
UNCLUTTER of that file will produce an
error message warning that "Bucket n points
at bucket x but succeeding index entry does
not." This happens because the final tests
of bucket consistency are performed against
the last bucket, if one exists; the last
bucket, however, is "refetched" using the
highest key found in the file. If the
previous bucket contained no data, the
bucket BEFORE that one is fetched, and
all sorts of evils arise. Thus, if we find
a bucket with all entries deleted and
expunged, do not leave a previous-bucket
pointer around for the next bucket to make
an erroneous consistency check with.
455 RMS2U2.LNK Q345008 (RL,2-Feb-84) Clean all references to RMSMES
RMSLIB.R36 out of RMSUTL, and change all calls to TX$TOUT
RMSM2 and TX$APP to use TX$OUT and TX$RPT in RMSM2.
RMSMAC Change UTLxxx modules to determine key type
UTLACT and to pass correct key or record datatype
UTLENV information to RMSM2 when the ^S control code
UTLEXT is used. Use other codes when possible.
UTLMSC Change all RMSMES format statements to control
UTLSYM strings for RMSM2. Modify RMSM2 to put out
UTLTOP any type of RMS key when called with the ^S
UTLUSE control code. Finally, fix a bug in UTLUSE
UTLVFY which was fixed in maintenance long ago (see
edit 63).
456 RMSM2 (RL,6-Feb-84) TXURFA writes RFAs backwards.
457 RMSASC (RL,23-Feb-84) The record reading loop in
GETASC subtracts 1 from the remaining buffer
space and then checks to see if it is LEQ 0.
This should be "LSS 0".
460 RMSSPT (RL,12-Mar-84) Edit 54 (in COMPRESS) does not
correctly check for duplicates as was intended.
461 RMSFRE (RL,8-May-84) Fix $FREE to setup the FST
correctly on entrance.
462 RMSUSR (RL,12-Jul-84) Fix reference to XABALL$K_BID
in $XABALL_INIT; should be XAB$K_BID.

547 RMSDIR, RMSD20, RMSERS (AN, 11-Jan-85) Fix $Erase & $Rename
RMSDPO, RMSCLS, RMSROP
550 RMSDSI, RMSEXT, RMSOPN, (RL, 14-Jan-85) Fix to make
RMSUIN FFF calling work:
DSI : use ORG = none for non-RMS files,
based on file class rather than
on the record format;
EXT : add R$NULL declaration;
OPN : pass FST in FAB, etc., when
calling F$OPEN;
UIN : declare a LINKAGE for $FFFINT in
order to access register arguments.
551 RMSUSR (RL, 15-Jan-85) Changes to RMSUSR to
make FFF compile cleanly. Add $FFFINT
calling macro, etc.
552 RMSSYM.MPR (AN, 15-Jan-85) Fix ancient bug in runtime
initialization of XABs from MACRO

560 FALDAP, RMSROP (AN,7-Feb-85) Refine datatype default further
561 FALDAP, DAP, RMSRRE (AN,14-Feb-85) Fix CRC, RFA, and RSZ errors
562 UTLTOP, UTLSET (RL,6-Mar-85) Create UTLSET.B36 with routine
UTLSET (called from RMSUTL in UTLTOP). This
routine merges RMS-SINGLE-SECTION.EXE into
the RMSUTL image and saves the RMS entry
vector address; it also sets up PDVs and a
few other things. One then SAVEs the file.
On subsequent runs, UTLSET sets up the RMS
entry vector with the SDVEC% JSYS.
This avoids the problems arising from RMS's
move into a non-zero section. RMSUTL needs
RMS in section zero, and this puts the code
together without collision between global
symbols.
563 RMSUSR (RL,28-Mar-85) Add TYP block classes for
FFF files to RMSUSR; they were previously
only in FFFUSR.R36.

to fixed sequential files
and clear RSL in NAM block on errors

603 FALDAP (AN, 20-Jan-86) Don't send extra attrs to VAX
on Directory-List function
604 RMSDIR (TGS, 14-Feb-86) Fix 'Bad JFN' bug: Don't
return JFN to FAB during $PARSE iff file
file is remote OR JFN is parse-only.
Partially supplanted by edit 615.
605 DAP,FALDAP,DAP.REQ (AN, 27-Jan-86) Handle oversize VMS RFA's
606 DAP,FALDAP (AN, 31-Jan-86) Fix IMR with more UAPointer()s

function code to Create for remote CIF.
610 DAP,FALDAP,RMSDIS (TGS, 7-Mar-86) Rewrite DAP extended key
RMSLIB XAB attributes so remote $CREATE works (also
added DAP KNM handling). If delete-on-close
and CRC-checking have been set during Access-
complete-close, do not compare checksums.
Fix directory/list from VMS when RMS thinks
the local file is LSA.
611 FALDAP (TGS, 24-Mar-86) Find lost RFAs, which weren't
getting returned in STATUS messages, and were
getting ignored in D$GCTL.
612 DAP.REQ (TGS, 25-Mar-86) Increased DAP$k_Buffer_Size
to 8192 (20000 octal)
613 RMSUSR.R36,DAP.B36, (SC, 27-Mar-86) Added DIL8 type class to
RMSOPN.B36,RMSRRE.B36, provide support for DIL formatted 8-bit

sequential files: the page count calaculation
goes negative, PMAP% fails.
623 DAP (TGS, 9-Jun-86) Fix remote keyed $GET.
624 RMSRRE (TGS, 10-Jun-86) Don't require fixed-length
remote $GET user buffers to be an even
number of words.
625 RMSD20 (GAS, 10-Jun-86) Dot bug caused low memory to
be trashed at the RNAMF in RL$RENAME.
626 RMSUSR (GAS, 12-Jun-86) Add FAB picture; fix NAM
picture; NAM$M_PWD and NAM$M_SYNCHK were
defined wrong; XABPRO masks defined wrong.
627 RMSROP (TGS, 11-Jun-86) Always request KEY display
on remote indexed $Open if partner supports
it.
630 FALDAP,DAPSUB (TGS, 12-Jun-86) Processing remote key
fields on $Get no longer assumes the
indexed dtp is unchanged from a previous
$Get.
631 RMSD20 (TGS, 13,Jun-86) Set GJ%FOU, not %NEW, on
$Rename's newfab JFN.
632 DAP.REQ,FALDAP (TGS, 16-Jun-86) Add some more RMS-to-DAP
error code conversions so normal errors
are not signalled as DPE's.
633 FALDAP (GAS, 17-Jun-86) Make wild deletes work for
PDP-11 system access to RMSFAL.
634 DEBCMD (asp, 17-Jun-86) Re-order TYP class values

is received without preceeding volume
and directory NAME messages, eat message.
642 RMSMSC (TGS, 27-Jun-86) Old extended addressing
bug in MOVEKEY was randomly shuffling
user-section memory before a string
copy.
643 FALDAP (GAS 27-Jun-86) Always return main attributes
even though access msg didnt say to if it is a
OPEN, CREATE, or SUBMIT message (used by RT11),

647 DAP, FALDAP, RMSUSR (GAS, 12-Jul-86) Fix image reads from TOPS-10
NFT (he does SEQ image access). When reading
an attributes message, default the datatype to
IMAGE, and if image from a LCG machine default
the BSZ to 36 and MRS to 512 if they weren't
given. Also fix FAB picture in RMSUSR.
650 RMSDIR (GAS, 17-Jul-86) DAP$SEARCH didn't update the
NAM block lengths and pointers properly for
remote files breaking DIU's directory command
and wildcards to/from remotes.
651 RMSDIR (GAS, 17-Jul-86) DAP$SEARCH and DAP$MERGE
didn't stop on a null causing it not to work
sometimes and in particular on TOPS-10
filenames.
652 DAP (GAS, 25-Jul-86) If we are talking to an old
non-RMS TOPS-20 program then add two to the MRS
if the RFM is STM and default the FOP to SUP if
none specified. This makes DIT (DIL) work.
653 DAP (GAS, 30-Jul-86) Don't default the MRS to 512
unless the RFM is UDF and all of the following
is true: no MRS was specified, we are talking
to a 10 or 20, the TYP is IMAGE (correcting
part of edit 647).
