MOUNTR.DOC -- Changes from V4(63) TO V4A(130)
June 1981
1.0 SUMMARY
Version 4A is a maintenance release of MOUNTR and contains bug fixes
and minor enhancements.
MOUNTR should be compiled under TOPS-20 V4 or later. For the
successful operation of MOUNTR the edits described in the file
MOUNTR.BWR should be installed in the appropriate modules. After
installing these edits sites should reassemble ORNMAC, OPRQSR and
relink ORION. In addition certain installations may wish to install
optional edits documented in the file MOUNTR.EDT. Sites using
AUTOPATCH for the TOPS-20 Monitor should not install patches from
MOUNTR.EDT however these patches will be included on some future
AUTOPATCH tape.
2.0 EXTERNAL CHANGES
1.0 No existing commands or actions have been changed.
2.0 Mount requests displayed to the operator are accompanied by
a ringing of the terminal bell to attract the operator's
attention.
3.0 The following error message has been added.
--MOUNTR System Task Error--
Account record not written (user information) Reason:
(reason)
In the past this error caused MOUNTR to crash.
4.0 The OPR display for SHOW STATUS DISK-DRIVE has been changed
to give more complete information.
5.0 Certain displays have been changed to include the controller
field for a disk controller. This field is used only with
RP20 disks.
3.0 KNOWN BUGS AND DEFICIENCIES
None.
4.0 INSTALLATION INSTRUCTIONS
MOUNTR.DOC Page 3
The following is for informational purposes only. The edits described
in the file MOUNTR.BWR are necessary for the successful assembly and
operation of MOUNTR and should be installed in the appropriate
modules. MOUNTR can be assembled using the file MOUNTR.CTL after
appropriate modifications have been made to reflect logical names,
structures, directories, etc. as required by the installation.
The following is a sample installation session:
@! ALL FILES MENTIONED CAN BE FOUND ON THE TOPS-20 DISTRIBUTION TAPE
@! UNLESS ANOTHER SOURCE IS MENTIONED.
@
@! MOUNT THE TAPE PROVIDED AND COPY ALL MOUNTR.* FILES TO THE INSTALLATION
@! AREA. WE ASSUME THAT THIS AREA IS CALLED PS:<4A-MOUNTR>
@
@! EDIT THE FILE ORNMAC.MAC SUPPLIED WITH THE TOPS-20 DISTRIBUTION TAPE
@! AS SHOWN IN THE BEWARE FILE IF NECESSARY. IT WILL NOT BE NECESSARY IF
@! THIS EDIT WAS INSTALLED IN THE PAST NOR WILL THE REBUILDING OF ORION.
@!
@! EDIT THE FILE OPRQSR.MAC SUPPLIED WITH THE TOPS-20 DISTRIBUTION TAPE
@! AS SHOWN IN THE BEWARE FILE IF NECESSARY. IT WILL NOT BE NECESSARY IF
@! THIS EDIT WAS INSTALLED IN THE PAST NOR WILL THE REBUILDING OF ORION.
@
@! NOW COMPILE THE EDITED ORNMAC. YOU MAY USE THE FILE OPERATOR.CTL
@! FROM THE DISTRIBUTION TAPE TO DO THIS OR YOU MAY DO IT AS SHOWN
@! THE FILE GALCNF.UNV MUST BE AVAILABLE FOR THIS COMPILATION.
@COMPILE ORNMAC
MACRO: ORNMAC
BUILDING A GALAXY-20 ORNMAC
EXIT
@
@! NOW COMPILE OPRQSR USING THE UNIVERSAL FILE ORNMAC.UNV WHICH YOU HAVE
@! JUST COMPILED.
@! THE FILE QSRMAC.UNV MUST BE AVAILABLE FOR THIS COMPILATION IN ADDITION TO
@! ORNMAC.UNV
@COMPILE OPRQSR
MACRO: OPRQSR
EXIT
@! WE WILL NOW RELINK ORION. WE ASSUME ALL REL FILES OTHER THAN OPRQSR ARE ON
@! LOGICAL DEVICE PG: THE FOLLOWING STEP MAY BE ACCOMPLISHED BY SUBMITTING
@! OPERATOR.CTL (FROM THE TOPS-20 DISTRIBUTION TAPE) AFTER ANY NECESSARY
@! MODIFICATIONS HAVE BEEN MADE.
@! THE FILE ARMAIL.REL (FROM THE TOPS-20 DISTRIBUTION TAPE) IS ASSUMED TO BE
@! ON SYS:
@! THE FILES OPRCMD.REL, CNTTAB.REL (DECNET ONLY), GLXINI.REL AND NCPTAB.REL
@! ARE ALSO NEEDED. FOR THIS LOAD THEY ARE ASSUMED TO BE ON DSK:
@
@! THE FOLLOWING SEQUENCE OF COMMANDS CAN BE USED IN PLACE OF OPERATOR.CTL
@
@DEFINE M4A: PS:<4A-MOUNTR>
@LOAD PG:ORION,M4A:OPRQSR,PG:OPRPAR,PG:OPRLOG,PG:OPRNET,PG:OPRERR,SYS:ARMAIL
LINK: Loading
EXIT
MOUNTR.DOC Page 4
@! NOW WE WILL SAVE THE NEW ORION ON THE SYSTEM AREA IN THIS CASE WE ASSUME
@! THAT THIS AREA IS PS:<NEW-SUBSYS>
@
@SAVE PS:<NEW-SUBSYS>ORION
<NEW-SUBSYS>ORION.EXE.2 Saved
@
@! ORION IS NOW REBUILT AND INSTALLED.
@
@! TO INSTALL MOUNTR SIMPLY COPY THE FILE MOUNTR.EXE TO THE SYSTEM AREA
@COPY MOUNTR.EXE PS:<NEW-SUBSYS>MOUNTR.EXE
MOUNTR.EXE.1 PS:<NEW-SUBSYS>MOUNTR.EXE.2 [OK]
@
@! SYSJOB WILL HAVE TO BE RELOADED IN ORDER FOR THE NEW VERSIONS OF MOUNTR
@! AND ORION TO BE USED. A RELOAD OF THE SYSTEM WILL ALSO CAUSE THE NEW
@! VERSIONS TO BE USED.
@
@! IF IT BECOMES NECESSARY TO REBUILD MOUNTR SIMPLY SUBMIT THE FILE
@! MOUNTR.CTL AFTER MAKING APPROPRIATE MODIFICATIONS SO THAT ALL PROPER
@! FILES MAY BE FOUND.

5.0 INTERNAL CHANGES
The following is for informational purposes only.
EDIT COMMENT
64 Get more unique PID name and enhance messages when
debugging.
65 Add RP20 Support.
66 Change symbol name to avoid a conflict with MONSYM. Also
fix a bug which prevented the printing of 2 error messages.
67 Do not ask the operator to key in volume identifiers when
initializing labelled tapes.
70 Store the device designator in the accounting block for
tapes. This prevents the account block from being
inadvertantly deleted.
71 This edit was replaced by edit 120.
MOUNTR.DOC Page 5
72 Correctly initialize register STR in routine KSST. Prevents
memory trashing bug.
73 Do not set OF%OFL when opening a tape drive. This allows
MOUNTR to check for drive offline.
74 Give more complete status for SHOW STATUS DISK-DRIVE.
75 Prevent MOUNTR from crashing if LPTSPL is spooling to tape
and the tape drive is set available.
76 More of edit 74, report drive offline.
77 Fix a bug which allowed a user to get an unlabelled tape
without the operator IDENTIFYing the tape.
100 Change an AC in the new RP20 code. Also change some symbol
names for future GALAXY (later removed).
101 Make significant changes to magtape accounting. Fixes many
errors in the usage records.
102 Remove some old unneeded code.
103 Format change to SHOW STATUS DISK-DRIVE display.
104 Fix a bug which caused a structure to be unmountable if a
DISMOUNT command with the REMOVE switch was cancelled.
105 Prevent USAGE JSYS failure by storing zeros in the account
block when a negative number is found. This edit was
removed when the problem which caused the incorrect negative
numbers was fixed.
106 Improve the processing of MOUNTR.CMD. This edit causes the
DEFAULT status to be used for all structures. Prior to this
edit DEFAULT affected only structures which had no other
command lines in MOUNTR.CMD.
107 Fix a bug which prevented account blocks from being zeroed
during their allocation.
MOUNTR.DOC Page 6
110 Display the user supplied remark, if any, during a tape set
request.
111 Remove edit 71.
112 Change the symbol names modified by edit 110 back to their
origional definitions.
113 Add MOUNTRs name and version number to the usage records
which it writes.
114 Make a format change to SHOW STATUS DISK-DRIVE display.
115 More of edit 77. Do not allow a user to get an unlabelled
tape without the operator IDENTIFYing it under any
circumstances.
116 This edit was removed.
117 Insure that account blocks are not destroyed by a tape volume
switch.
120 Reorganize the handling of structure accounting blocks to
make the times meaningful. Also rewrite edit 117 to fit
into this framework.
121 Ring the console bell when displaying a mount request.
122 Fix a bug which caused an operator generated structure
dismount request to remain active forever.
123 Change accounting code in routine VRA so that it is executed
before the tape drive is given to the user.
124 Add a new error message for the operator indicating failure
to write an accounting record. Also ignore failure of the
DIRST JSYS rather than crashing.
125 Prevent the loss of an account block when a non-regulated
structure is physically mounted. Also correct the test for
a domestic structure when doing accounting.
MOUNTR.DOC Page 7
126 Remove edit 116.
127 Remove edit 105 since this is a non-fatal error due to edit
124 and should never happen anymore due to edit 120.
130 Add local symbols which are usually found in universal files.
This change allows MOUNTR to be assembled using field image
software.
