 * 027 29-Jul-90 tmk Likewise the VMS V3 stuff - ancient history

 * 029 31-Jul-90 tmk Fix CWD command (via hack)
 * 030 31-Jul-90 tmk Fix assorted bugs preventing remote commands from working
 * 031 31-Jul-90 tmk Correctly handle interrupted remote commands

 * 040 29-Sep-90 tmk Add iswild() from FDC for C-Kermit 5A edit 157
 * 041 06-Oct-90 tmk Add filetype IMAGE support for outbound transfers. Note
 *		     that this doesn't currently work as the receiver overrides
 *		     it (must talk to fdc).
 * 042 06-Oct-90 tmk Make logfiles MRS=80. Being able to edit them outweighs
 *		     any use for un-split lines.
 * 043 17-Oct-90 wb  Make zclosf() remove delete mailboxes & deassign channels
 *                   used to talk to the subprocess, so quotas are not used
 *                   up after repeated mailbox use (installed by fdc).
 * 044 19-Oct-90 fdc Changed zxcmd() to use the fp[] arrays in the normal way,
 *                   and zsyscmd to call zxcmd(ZIFILE) rather than
 *                   zxcmd(ZSYSFN).  Got rid of all calls to system(), used
 *                   zsyscmd() instead, so commands like DIR could be
 *                   interrupted.  Made zoutdump() return(-1) rather than
 *                   exit() when "line too long for buffer", and increased
 *                   line output buffer from 1K to 4K.
 * 045 01-Nov-90 tmk Corrected behavior of error check on $create call so a
 *		     file supersede would work properly.
 * 046 01-Nov-90 tmk Clone binary flag to ofile_bmode so we have a consistent
 *		     view of this flag during file operations - the binary flag
 *		     tends to toggle when we don't want/expect it to.
 * 047 01-Nov-90 tmk Make IMAGE mode work. Note that image mode is only used
 *		     when VMS is sending a file, and includes all record
 *		     control characters not normally sent. Only useful in
 *		     unusual circumstances.
 * 048 01-Nov-90 tmk Remove spurious \n from zsoutl() which caused debug logs
 *		     to have spurious <CR>'s when viewed with editors.
 * 049 02-Nov-90 fdc Adapt to dynamic allocation of file i/o buffers.  Changes
 *                   are within #ifdef DYNAMIC..#else..#endif brackets.
 * 050 02-Nov-90 fdc Make zsyscmd() close inferior process.
 * 051 ??-???-?? ??? Add ckermit_init logical, return 0 on wildcard operations.
 * 052 24-Dec-90 tmk Fix performance problems after 32Kb w/ ASCII receives, fix
		     2-nulls-per-32Kb in binary mode bug (actually in ckcker.h,
		     this is a placeholder).
 * 053 13-Jan-91 tmk Add support for SET FILE RECORD-LENGTH.
 * 054 14-Jan-91 tmk Fix cases of /x/CR/LF/y/ and /x/CR/LF/y/CR/LF/ in ASCII
 *		     file receives.
 * 055 16-Jan-91 tmk Log requested file type to debug log when receiving.
 * 056 16-Jan-91 tmk Add support for all zstime() functions.
 * 057 17-Jan-91 tmk Add support for zchkspa() function.
 * 058 17-Jan-91 tmk Move debug() call into if clause in zxpand, per fdc.
 * 059 18-Jan-91 tmk Support remote (DECnet) file accesses.
 * 060 18-Jan-91 tmk Fix READ command.
 * 061 30-Jan-91 tmk Support creation of UNDEFINED file types for brain-dead
 *		     BASIC implementation.
 * 062 30-Jan-91 tmk Fix REMOTE commands when VERIFY is set.
 * 063 29-Mar-91 tmk Add padding factor for received text files to accomodate
 *		     space taken up by record delimiters (per fdc).
 * 064 29-Mar-91 gm  Remove unnecessary mem-mem moves during ASCII receives.
 *		     (Installed by tmk. To back out, #define OLD_WAY).
 * 065 30-Mar-91 tmk First pass at implementing LABELED. Send only, dummy
 *		     data records.
 * 066 02-Apr-91 tmk Finish first pass at LABELED. Send VMS filename, attri-
 *		     butes. Still need ACL's, "hidden" char. longword, recep-
 *		     tion.
 * 067 09-Apr-91 tmk LABELED bugfixes - VMSFILE is 70 bytes, not 74, use the
 *		     xab$w_lrl field instead of rab$w_rsz, fab$w_deq instead
 *		     of xab$w_rsz, fab$b_bks instead of xab$b_bkz, always pro-
 *		     cess an even multiple of 512 bytes when LABELED.
 * 068 14-Apr-91 tmk Don't use C definition of fab$b_journal as it doesn't ex-
 *		     ist before C V3.1. Compute it ourselves instead.
 * 069 15-Apr-91 tmk Initial work on retrieving ACL information for LABELED.
 * 070 16-Apr-91 tmk Make edits 066-069 compatible with DECnet.

 *		     zclosf() after zoutdump() error.
 * 076 21-Jun-91 tmk First pass on handling inbound LABELED files.
 * 077 14-Nov-91 tmk Fix zprint(), zmail() (need to use system() for these).
 *                   This is a partial backout of 044.
 * 078 14-Nov-91 tmk Various cleanups.  Delete files after successful mailing
 *		     or printing, remove dead code inside #ifdef COMMENT and
 *                   #ifdef OLD_WAY, fix typo in spawning message, make sure
 *                   all source lines < 80 chars.
 * 079 22-Nov-91 fdc Change zmail(), zprint() error return values to improve
 *		     error reporting.
 * 080 18-Jan-92 tmk Fix REMOTE so output from a remote command correctly dis-
 *		     plays on terminal. This has been broken since 040 or so.
 * 081 10-Jun-92 tmk Add William Bader's fix for fixed-length files which have
 *                   record attributes.
 * 082 03-Jul-92 tmk Fix really bad bug introduced in 081 (which made *all*

 * 087 04-Sep-92 tmk Fix bug reported by Chuck McMichael where C-K would not
 *		     set the FFB properly when receiving a labeled file which
 *		     did not have the FFB on a record boundary.
 * 088 09-Sep-92 tmk Fix Hunter Goatley's problem with SPAWN command ignoring
 *		     Ctrl-C.
 * 089 11-Sep-92  js Fixed malloc() in zmail().
 * 090 28-Oct-92 tmk Fix null-byte error introduced by 087. Gee, this looked
 *		     so simple when I designed it.
 * 091 02-Nov-92 tmk Start work on fixing spawn/push/remote commands, due to
 *		     popular whining.
 * 092 03-Nov-92 tmk Finish up initial 091 work. Vote for Kermit!
 * 093 03-Nov-92 fdc Change zkermini() to work with "-y" command-line option.

 * 098 16-May-93 fdc ANSIfication for GNU CC, from James Sturdevant, plus
 *                   add FAB$M_PRN to list of text-file types, for VMS batch
 *                   logs.
 * 099 07-Jun-93 fdc Fix calculation of file size in zchki(), fix declaration
 *                   of mbxnam[] (add one to size) to prevent overflow, which
 *                   would result in failure of server to respond to REMOTE
 *                   directory, etc.  Both fixes from Bill Glass.
 * 100 21-Jun-93 fdc file_date[] and attr_date[] declarations in zstime()
 *                   changed from long to unsigned long to prevent signed date
 *                   comparisons, which could prevent SET FILE COLLISION
 *                   UPDATE from working.  From James Sturdevant.
 * 101  8-Aug-93 fdc Add types to all function declarations.
 * 102 18-Aug-93 ttj Minor updates in zsattr() and do_label_recv() mainly to

 *                    Make zkself() retry a few times to avoid zombies on BYE.
 * 109  5-Apr-94 tmk  Fix xx->lengthk not being set in zsattr().
 * 110  8-Jun-94 tmk  Use private fab in zchki (fixes OPEN READ bug).
 * 111 17-Jun-94 tmk  Let zsattr() work even if there is no rights database.
 * 112  7-Jul-94 js   A couple small ANSIfications for gcc.
 * 113  7-Aug-94 fdc  Make zshcmd()/zsyscmd() return proper return code, with
 *                    help from Larry Henry at TWG.  Still not quite right...
 * 114 29-Sep-94 fdc  Increase max wildcard matches from 500 to 4096.

 * 120 31-May-96 fdc  Fix zfnqfp() to remove trailing .; if directory name.
 * 121 12-Jun-96 fdc  Prevent dereferencing null pointer in do_label_recv().
 * 122 23-Jun-96 fdc  Fix a bug in do_label_recv that I introduced in edit 121.
 * 123 21-Aug-96 fdc  Separate ZRFILE from ZIFILE so now we can have both.

 * 129 06-Sep-96 fdc  Fix zchki() to return -2 if blah.DIR;n is a directory.
 * 130 06-Sep-96 fdc  Fixes to isdir(), zstrip(), zchdir().
 * 131 17-Feb-97 fdc  Another fix to isdir() (free() was called too early).
 * 132 14-Jul-97 fdc  fgen() malloc'd but never freed filenames; isdir()
 *                    now handles directory files too (like [FOO]BAR.DIR;1).
 * 133 14-Jul-97 mb   New isdir() function uses sys$parse().
 * 134 15-Jul-97 fdc  Added cvtdir(); rewrote zchdir() to use it & new isdir().
 * 135 14-Aug-97 fdc  zopeni: Change mainline binary variable when switching
 *                    automatically from text to binary mode (cosmetic only).
 * 136 24-Aug-97 fdc  zhome: Return SYS$LOGIN value rather than HOME value.
 * 137 04-Sep-97 fdc  zchdir: use sys$setddir() rather than chdir() because
 *                    VMS 6.2 CRTL chdir() has bugs.
 * 138 06-Sep-97 fdc  zchdir again -- try one, then the other.  Add startupdir.
 * 139 04-Nov-97 fdc  Handle absolute/relative/standard/literal dir names.
 * 140 12-Dec-97 fdc  Fix fgen() to report directories if not told not to.
 * 141  1-Jan-98 fdc  Send and set file protections: zsattr(), zstime().
 * 142 15-Jan-98 fdc  Raised max number of files (MAXWLD) from 4K to 1024K.
 *                    and made the mtchs[] array dynamic.
 * 143 29-Jan-98 fdc  Make zshcmd() (RUN command) return proper status,
 *                    ditto for zxcmd(), and make both set pexitstat.
 *                    Also, added ckvmserrstr().
 * 144  8-Feb-98 lh   Add diagnostic message when SPAWN fails; handle files
 *                    with odd fixed record length; isdir() improvements.
 * 145  8-Feb-98 fdc  Slightly better handling of failures in zrmdir().
 * 146  3-May-98 fdc  Fix out-of-bounds cdate[] array reference.
 * 147  7-May-98 lh   another isdir() update; expanded mb (Apr-98) version.
 *               lh   Add REL_DIR item for do_label transfers.
 *               lh   FTN CC to handle zero-length records and overprinting.
 *               lh   Fix zltor for fspath and no match.
 *               fdc  Fix zmkdir to return 1 if >0 directories were created.
 * 148 28-Jun-98 fdc  Fix to odd-record-length code from edit 144, which broke
 *                    RESEND/REGET.  Added zgetfs().
 * 149  5-Sep-98 fdc  cdate[] array declaration needed to be 24, not 23.
 * 150 21-Dec-98 fdc  Added zrelname(), zgperm(), and ziperm().
 * 151 26-Jan-99 fdc  nzltor(): convert path format if other Kermit not VMS.
 * 152  8-Feb-99 lh   Fix constructions like "cd sys$manager" in isdir().
 * 153  8-Feb-99 fdc  Add zxrewind(), add support for recursion in fgen(),
 *                    make zgetfs call stat() to get size.
 *                    Fix chkfn() for connection log.
 * 154 17-Mar-99 lh   Add support for sending PRN files.
 * 155 15-Apr-99 fdc  Fix zmkdir() to tolerate long filenames.
 * 156 16-Apr-99 fdc  Add (nonworking) timeout support to get_subprc_line().
 *                    Somebody please look at this routine & fix it.  It's
 *                    supposed to time out and return after 1 second if nothing
 *                    comes from the subprocess, but instead it seems wait
 *                    forever.  To test, put VMS C-K in server mode and then
 *                    tell the client "remote host wait 00:00:30".  VMS C-K
 *                    is supposed to send back an empty data packet every
 *                    second but it doesn't.
 * 157 16-Apr-99 lh   Fix 156.
 * 158 20-Jun-99 fdc  Fix rinfill() to also work with mailboxes.  I don't see
 *                    how OPEN !READ/ READ/ CLOSE READ could ever have worked.
 * 159 22-Jul-99 lh   Add zcopy().
 * 160 23-Jul-99 fdc  Add lots of signed-vs-unsigned char casts.
 * 161 27-Jul-99 lh   Fix sys$synch() call in get_subprc_line().
 * 162 29-Jul-99 lh   Fixed get_subprc_line() keepalive performance.
 * 163 24-Aug-99 fdc  Fix do_label_send() broken by edit 160 (diagnosis by lh).
 * 164 02-Sep-99 fdc  Add nopush checks to zxcmd(), zshcmd(), and zsyscmd().
 * 165 19-Sep-99 lh   Fix zfnqfp() error return (NULL, not -1).
 *                    Subtly alter fgen()'s expansion of wildcards (*.* -> .*).
 * 166 06-Oct-99 lh   Fill in zchko.  Change log file error handling, zopen

	b) Zero-terminate the TYPE by replacing the ; with a zero
	c) Make sure TYPE is .DIR
	d) replace the closing ] with a .
	e) replace the . that starts the file TYPE with a ]

 * it's horribly painful to change a file's creation date after-the-fact we
 * call zstime with an argument  of 2 to pre-set the date when creating the
 * file. An argument of 0 (which the main-line code thinks sets the date of
 * the output file) returns success but does nothing.  Note that an invalid
 * or missing attribute packet will cause $bintim to return an error, which
 * causes the routine to exit. Since we pre-set the binary time to zero, we
 * will create the file "now", or say the incoming file is newer, whichever

    The purpose of this routine is to determine whether the file specified
    by *s would be in the current default directory or not.

    Inputs:
	*s = filename to check, can be just a filename or full path

    Outputs:
	0 = in the current default directory
        nonzero = not in the current directory

    Algorithm:
	Uses SYS$PARSE.  As long as the current default directory is not
	on a remote DECnet node, SYS$PARSE will return the Directory ID
	of the directory where the parsed filename would be found.  This
	means all we need do is parse both the default directory and the
	filename passed to us and compare DIDs (as well as make sure the
	two DIDs reference the same disk).  If so, it doesn't matter how
	convoluted the filename passed to us is, or what logical names
	may be involved, SYS$PARSE will tell us with certainty if it
	resolves to the current directory or not.

	However, if the current default directory is on a remote DECnet
	node, this information is not available (since SYS$PARSE executes
	locally, not remotely).  In this case, SYS$PARSE will still expand
	the filename as much as possible and then we can simply compare
	the default directory with the directory reference returned by the
	parse of the filename in *s using a simple string compare.  Since
	we cannot evaluate remote logical names, this may cause a false
	negative to occur if the user is playing games with the filename,
	but it guarantees that we do not get a false positive.
