/*
 * Title:	version.c - Directory-Editor Release history
 * Author:	Thomas E. Dickey
 * Created:	28 Aug 1984
 * Last update:			In-progress: restructure 'dircmd', 'getraw'.
 *
 *	v951027 - prerelease testing
 *
 *	----	27 Oct 1995	Added "create" command.  Modified BROWSE to
 *				allow it to read locked files by using shared
 *				I/O.
 *
 *	v951026 - prerelease testing
 *
 *	----	25 Oct 1995	Corrected checks for deleted files in
 *				'dirfind()'.  Corrected parenthesis in
 *				'isowner()' that prevented privileged users
 *				from setting file-protection.  Animated the
 *				"Working..." message.   
 *
 * 	----	24 Oct 1995	added "USER" column and corresponding sort
 *				commands.
 *
 * 	----	22 Oct 1995	corrected bug in ^P (set protection) command
 *				due to difference between DEC-C/VAX-C ctype.h
 *
 *				modified "/dlong" to show seconds if command is
 *				repeated.
 *
 *				corrected (pruned) redundant pathname text that
 *				arises from rooted-logical expansions.
 *
 * 	----	21 Oct 1995	final phase of mods for prototyping functions,
 *				clean-compile with DEC-C.
 *
 *	----	06 Jun 1995	more prototypes (almost done)
 *
 *	----	28 May 1995	use <stdarg.h> rather than VARARGS hack
 *
 *	v950319 ported to AXP in VAX-C compatibility mode
 *
 *	----	19 Feb 1995	Using AXP demo machine with DEC-C, first phase
 *				of mods to prototype all functions.
 *
 *	---- stopped keeping track of absolute build numbers, converted to rcs
 *
 *	x2149	22 Apr 1993	Rebuilt at Software Productivity Consortium
 *
 * 	----	05 Dec 1989	vms 5.1 altered "prvdef.h" file so that
 *				PRV$V_???  is no longer defined.  altered
 *				sysrights.c and callers isowner.c, cmpprot.c to
 *				recompile.
 *
 *				patched out trace in DCLARG for bug found in
 *				89/03/20 (haven't seen it under vms 5.1, also
 *				conflicts with rebuild).
 *
 *				corrected typo in 'dirent.c' (wrong
 *				variable-type, which previous compilers
 *				accepted & dealt with properly).
 *
 *	----	20 Mar 1989	found intermittent problem with RMS where an
 *				illegal status code is returned -- manifested
 *				in a 0x10000 code returned from SYS$PARSE call
 *				in DCLARG.
 *
 *	----	06 Mar 1989	increased BROWSE's limit on the size of the
 *				fseek-vector which it maintains; also increased
 *				FLIST's limit on log-file width to 132 from 80.
 *
 *	----	24 Feb 1989	added procedure 'flist_chdir()' to encapsulate
 *				(and log) changes of working directory.
 *
 *				modified 'getraw()' so that command-file input
 *				is discarded except for lines beginning with
 *				'$' (leading blanks optional).  This lets me
 *				use the /LOG output directly as a command-file.
 *
 *				modified 'browse.c' so that the version which
 *				is linked into FLIST will log output in a form
 *				that can be replayed in FLIST's command-file.
 *
 *	----	16 Feb 1989	added ".DIF$*", ".SHO" and ".TJL" to list of
 *				file-types which are not prompted on deletion
 *				(fldlet.c).
 *
 *	----	09 Feb 1989	mod for vms5.0; may set delete-enable on files
 *				to rename them, restore original protection
 *				after renaming.
 *
 *	----	02 Feb 1989	port to vms5.0; minor fix to flsort; also there
 *				use 'qsort()' instead of the previous
 *				selection-sort.
 *
 *	----	17 Nov 1988	FLIST on SYS$SYSROOT suddenly changes to
 *				SYS$COMMON, and the list is not sorted
 *				properly.
 *
 *	----	04 Nov 1988	added expiration-date stuff to FLIST (a la
 *				REVISED).  Also, corrected places where
 *				member/group codes were masked to a single
 *				byte.
 *
 *	----	03 Nov 1988	the output from my tar program is not readable
 *				by BROWSE, though other STMLF files are.
 *
 *	----	14 Oct 1988	sometimes FLIST's command history gets
 *				garbaged.
 *
 *				sometimes after an UPDATE command in FLIST,
 *				PURGE thinks it has found a file which was
 *				protected, even though it is successfully
 *				removed.
 *
 *				FLIST does not recognize rooted device names,
 *				e.g., a delete applied to BOOCH_:[ADT]X.LIS
 *				becomes BOOCH_:[000000.ADT]X.LIS, which it does
 *				not like.
 *
 *	----	11 Oct 1988	corrected place in 'dirarg.c' where "/o" alone
 *				caused crash.  added ".DIA" to temp-file types
 *				in 'fldlet.c'
 *
 *	----	05 Oct 1988	the uid+gid display for pyster+dickey is
 *				wrong...should convert to names
 *
 *	----	03 Oct 1988	should update using DEC's current acpdef.h files
 *
 *	----	16 Sep 1988	corrected "purge" command, which crashed if too
 *				many versions were protected, since the
 *				message-buffer overflow check was wrong.
 *
 *	----	22 Aug 1988	added test in BROWSE to ensure that we have a
 *				filename!
 *
 *	----	17 Aug 1988	modified 'termsize.c' and 'getraw.c' so they
 *				use SYS$COMMAND rather than SYS$INPUT so that
 *				VTSIZE works in a LOGIN.COM (works either way
 *				with FLIST and BROWSE).
 *
 *	----	16 Aug 1988	corrected 'dirent_conv()', guarding better
 *				against buffer overflow on very long lines
 *				(i.e., > CRT_COLS).
 *
 *				relinked both flist, browse; increased size by
 *				about 16 blocks (may be because of VMS 4.7
 *				upgrade).
 *
 *	----	15 Aug 1988	observed bugs when helping sam gregory
 *				straighten out file protections for [.oldcamp]
 *				(they weren't readable):
 *				(a) had a very long display line, which would
 *				    have been longer than 132 characters before
 *				    truncation.  this caused a segment
 *				    violation.
 *				(b) at one point I lost the oldest part of the
 *				    command history.
 *
 *	----	11 Jul 1988	Permit '-' in filenames.
 *
 *	----	01 Jul 1988	Added command-table entry for LSEDIT (a la
 *				EDIT).  Note that FLIST will accept
 *				LSEDIT/EDIT/VIEW now to view a list (should
 *				plug it).
 *
 *	----	29 Jun 1988	Stripped parity bit in output-lines so that
 *				boldface/highlighting work properly on
 *				vt200-class terminals.
 *
 *	----	16 Jun 1988	Tried CC's /INCLUDE option so I could move the
 *				".h" files into a common directory; this did
 *				not work: it told me that I exceeded my
 *				enqueue-quota.
 *
 *				Relinked sortx; note that link/nodebug does not
 *				appear to do anything.
 *
 *	----	15 Jun 1988	Recompiled objects (userc.olb, fl.obj,
 *				browse.obj) and relinked.  To do this, copied
 *				some include-files from home into [.c] and
 *				[.d], since the VMS C-compiler's search rules
 *				have changed since I used it last (should fix
 *				REDO.COM).  Will test against the new
 *				executables.
 *
 *	----	13 Jun 1988	Moved to Software Productivity Consortium. 
 *				Most items work as-is, but FLIST and BROWSE
 *				executables sometimes crash.  For example, the
 *				"find" command in FLIST.
 *
 *	x2062	08 Oct 1985	Added code in CRT-module to detect change of
 *				terminal-size (especially after spawned commands).
 *				Used this to support /WIDTH command which lets
 *				one toggle 80/132 column mode.  Added arguments
 *				to HELP-command (from PROTECT, we go directly
 *				to the PROTECTION help-entry).
 *
 *	x2051	24 Sep 1985	Decode SET, SHOW as '/', '?' command-prefixes.
 *				Added VMS-style aliases /PROTECTION and ?DAYTIME
 *				to exploit this.  Added code in command-parser
 *				to generate message listing range of close-match
 *				keywords if no match was found.
 *
 *	x1998	14 Sep 1985	Amended READ command so that explicit update
 *				is done via UPDATE command.  If user types
 *				READ, existing database entries are not reopened.
 *
 *				Corrected collating order: VMS apparently sorts
 *				filenames counting trailing '.'
 *
 *				Enhanced wildcard comparison to recognize "..."
 *				in pathnames (fixes merge-problem with readlist).
 *
 *	x1957	26 Aug 1985	Amended /CWIDTH code so that we recompute on
 *				exit from a directory, and so that most operations
 *				which alter 'ccolumns' can result in a screen
 *				refresh (except indirect RENAME-path).
 *
 *				/CWIDTH without arguments recomputes 'ccolumns'
 *
 *				Link the release-copy /NOTRACEBACK since this is
 *				necessary to install-with-privilege (needed in
 *				turn for the SHELL command).
 *
 *	x1946	17 Aug 1985	Corrected (compiler hole) bug in '?FIND', made
 *				it stacked/hierarchical.
 *
 *				Make '.LOG' file receive everything that '.LIS'
 *				file does (i.e., results of '?READ').
 *
 *				Some enhancements to BROWSE program.
 *
 *	x1924	31 Jul 1985	Completed recoding to "structured heap" for all
 *				data objects.
 *
 *				Permit EDIT-directory command to accept options
 *				(except /COMMAND, /LOG and /FAST).
 *
 *				Permit wildcard-RENAME operation.
 *
 *				Added code to pack display when exiting from a
 *				level.
 *
 *				Added keyword 'UPDATE' for next-release work.
 *				Added '?READ' command.
 *
 *	x1835	06 Jul 1985	Corrected multi-quit screen refresh in 'dircmd'.
 *				Added "true" type-ahead test in 'getraw'.
 *
 *				Added "SHELL" and "?FIND" commands.  Altered
 *				/HOLD-operation so that we skip some before
 *				prompt if there is an error.  Reset keypad
 *				mode before calling librarian-help-facility.
 *
 *				Added /BEFORE, /SINCE options to do date-select.
 *				Also options /AFTER, /BACKUP, /CREATED and
 *				/MODIFIED as synonyms (to make it look more like
 *				VMS).
 *
 *				Upgrade to CC2.0; minor (but frustrating) fixes.
 *
 *				Revised 'nameheap' so that we use a single
 *				tagged heap (provides unique strings among levels)
 *				Used this also to support 'pathlist' (i.e., a
 *				directory-RENAME affects all levels).
 *
 *	x1667	24 May 1985	Added '/' command, '/CWIDTH' command.  Do log
 *				entry for set/show commands which operate on
 *				the current entry.
 *
 *	x1645	18 May 1985	Restructured 'dircmd' module so that all key
 *				definitions are via a string-table.  Also, the
 *				vcmd-tables are both in the same format.  We
 *				still use separate decoding for display (/,?)
 *				and file (DCL) commands.  The string-table makes
 *				log-files all in a readable format.
 *
 *				Corrected help-interface for VMS 4.x, which
 *				returns a different pathname for system files
 *				in GETJPI (see: whoami).
 *
 *				/FORWARD and /BACKWARD now accept a line-count
 *				argument.  Use this in keypad to set direction
 *				flag (0 lines).  Added '/PAGE' command to handle
 *				scroll-in-current-direction.
 *
 *	x1537	27 Apr 1985	Changed VAX/750-sid for re-issue.  'edtcmd'
 *				module is broken out, provides command-history
 *				and editing for BROWSE.  Put spurious sid-test
 *				in 'dclarg'.
 *
 *	x1517	20 Apr 1985	Added VAX/785-sid for re-issue.  In-progress
 *				for 'edtcmd' module; not included.
 *
 *				Added '/LOG' option to FLIST (not complete)
 *
 *	x1480	11 Apr 1985	Fixed 'pathup' by making it translate logical
 *				devices (fixed sys-manager bug).
 *
 *				Added /COMMAND options to both FLIST and BROWSE.
 *				'getraw' permits nested command-files.
 *
 *				Redid BROWSE's "X" as a CTRL/X AST.
 *
 *				Added '?MEMORY' command, put it on ',' keypad.
 *
 *	x1439	26 Mar 1985	Released second-version (with ATC's 730 in the
 *				SID-list).
 *
 *				Added column-types IDENTIFIER, LENGTH, with
 *				their associated sort-commands.
 *
 *				Provided interface to VMS-help (librarian
 *				routine).  Make /DS, /DL commands a 3-state
 *				switch.
 *
 *	x1421	14 Mar 1985	Renamed this program to FLIST; released first
 *				version for local use on ATC/Shelton VMS systems.
 *
 *				Added CTRL/C-ast to do cleanup.  Also require
 *				screen-height to be at least 4 lines.
 *
 *	x1412	11 Mar 1985	Added code to 'flrnam', 'dirpath' to properly
 *				rename pathnames when a directory is renamed.
 *
 *				Permit (wildcard) file specification in PROTECT.
 *				Added 'dirent_isdir' (common).  The 'dirfind'
 *				search 'forward' argument, if negative, uses the
 *				prevailing direction-flag: used in DELETE, PURGE
 *				and PROTECT.
 *
 *				Init flcols from main only (to make it inherit
 *				properly).  Restrict 'dirent_col' to keep at
 *				least 10 columns in command-field.
 *
 *	x1360	02 Mar 1985	Revised O (/OVER) command of BROWSE to do
 *				2-state toggle, or accept argument.  Also,
 *				corrected overstrike/highlighting
 *				(space by '_').
 *
 *				Added code to 'getraw' which tests the system
 *				identification register against known values,
 *				and garbages the input stream if a mismatch
 *				occurs.
 *
 *				Added "magic" (undocumented) function to copy
 *				date from one file to another: If /MARK is set,
 *				then a repeated ^D on another file will cause
 *				FLIST to copy date,protection from the marked
 *				file.
 *
 *				Added fatal-error message to 'BROWSE' ('erstat'),
 *				and truncate filename via 'more_name'.  Modified
 *				/JOIN-option in BROWSE to both omit binary files
 *				(by record-size) and to do joining if no trailing
 *				linefeed was found.
 *
 *	x1327	07 Feb 1985	Corrected INSPECT function (wasn't checking for
 *				at least one legal record; assumed I could always
 *				read a record).  Also, split 'dirseek_spec' into
 *				two levels so that I can support implicit
 *				wildpaths in INSPECT and VERIFY (was an error
 *				since 'dirfind' did not overlap properly with
 *				the VMS-search).  Make a 30-page stack in link,
 *				this seems to get rid of a runtime fault (?).
 *				(This seems a large stack; I tested it down to
 *				an 8-level directory.  With a 20-page stack I
 *				get a protection violation about 4-5 levels down.)
 *	x1298	02 Feb 1985	Corrected use of alarms in BROWSE.  Fixed ACPLOOK
 *				for (special?) case of 0-size of indexed files.
 *				Added 'crt_qsgr' entry to fix calls by SNAPSHOT.
 *				Reduce sys-search from 'dclarg'.  Revised the
 *				handling of 'readlist' (better pruning) in
 *				'dirread' module.  Added scrolling margin code
 *				to 'crt' module (making VT100 faster).  Do
 *				better cleanup/reset of terminal on exit and
 *				spawning.
 *	x1240	20 Jan 1985	Extensions to BROWSE (I,J, /TRIM) and rationalized
 *				its use of scale-mode and repeat-factor.
 *				Added crt-reset code to reset scrolling margins,
 *				and smooth-scroll on entries/re-entries.
 *	x1230	08 Jan 1985	Renamed BACKUP and REVISED qualifiers to
 *				DBACKUP and DREVISED.  Separate /NOO and /NOP
 *				tests in column-setup and sorting.
 *				Renamed 'FINDNXT' to 'NEXT', removed unneeded
 *				parsing from 'dirfind' module (faster).
 *	x1216	30 Dec 1984	Added "/SBACKUP", "/SCREATED", "/SREVISED" and
 *				"/SWEEK".  Added relative-number scrolling.
 *				Added "/MARK", "/NOMARK" (keypad-select), and
 *				highlight selected name, to show state.  Made
 *				this re-entrant in 'fledit'.
 *				Corrected error returns in 'chprot', 'setprot'
 *				and 'flprot'.  Added "/CLEFT", "/CRIGHT" and
 *				"NFIND".  Added "/DLONG", "/DSHORT".
 *	x1133	21 Dec 1984	Fixed bug in /SHOUR caused by flakey system
 *				code; permit system user to change protection.
 *				Re-coded 'cmdstk' so it uses a single-page
 *				buffer (instead of a linked list) to cut
 *				paging.  Reduced (by recoding 'dirent_chop'
 *				and new interface) the number of times I use
 *				SYS$PARSE; also use the same FAB for SYS$SEARCH
 *				and SYS$OPEN (reduces both CPU time, as well
 *				as paging across DECNET).  Provide ^D,^E,^F
 *				in command-line edit (a la VMS4.0).
 *	x1063	12 Dec 1984	Use ACP to speed up directory-read.  Added
 *				"?QUOTA", "/SFORMAT", and "/SATTRIBUTE".
 *				Added 'nameheap', to manage longer names for
 *				VMS 4.0, added PATH column-type ("/columns").
 *	x1012	03 Dec 1984	Added 'X' command to BROWSE (abort skip/search).
 *				Use 'putraw' to bypass Unix I/O bug.
 *				Added FORMAT, ATTRIBUTE column types, added
 *				INSPECT command.  Use ACP for change-protect
 *				('setprot', 'chprot' routines).
 *	x971	06 Nov 1984,	Improved crt-driver, improved BROWSE.
 *	x965	24 Oct 1984,	Cleanup of BROWSE, added 'sysfom' timer, broke
 *				out 'cmdstk'.
 *	x941	17 Oct 1984,	RMS-BROWSE, snapshot (^K), put locked-files at
 *				top of date-sort, put ^K, ^W into 'dircmd_GET'.
 *	x929	28 Sep 1984,	cleanup of RMS I/O (no more Unix file I/O,
 *				except via 'printf').
 *	x883	04 Sep 1984,	"/columns", multi-level quit, use "import" to
 *				reduce map-size.
 *	x854	29 Aug 1984,	"?"-prefix commands, cleanup of buffer sizes,
 *				use VAX string stuff.
