This removes a lot of overhead. * Add code to gtdir() for V4.x. * 019 12-Jun-89 mab Add PWP's encode logic * 020 09-Jul-89 mab Add logic to check for system() availability * 021 10-Jul-89 mab Fix SHOW USER USERNAME. Added space after 'SHOW USER'. * 022 27-Sep-89 mab Added zmail/zprint, plus added changes from CKUFIO.C * 023 01-Dec-89 mab Add RMS file support * 024 20-Jul-90 wb Add support for old VAX C & VMS versions + zstrip & rename * 025 29-Jul-90 tmk Change space command to show avail, not used (match spec) * 026 29-Jul-90 tmk Hack out the RMS stuff - it can come back when it works * 027 29-Jul-90 tmk Likewise the VMS V3 stuff - ancient history * 028 29-Jul-90 tmk Replace the attribute stuff. It now works. * 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 * 032 04-Aug-90 tmk Start work on full RMS support for input files * 033 04-Aug-90 tmk Tack LF on end of subprocess output lines * 034 04-Aug-90 tmk Complete work on full RMS support for input files * 035 04-Aug-90 tmk Add support for Fortran CC, fill in recfm data * 036 05-Aug-90 tmk Add trailing CRLF on print format files * 037 12-Aug-90 tmk Start work on full RMS support for output files * 038 12-Aug-90 tmk Honor first free byte (FFB) on SENDs * 039 13-Aug-90 tmk Finished first cut of full RMS support for output files * 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 '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. * 071 21-May-91 tmk Address R. Weiner QAR item 2 (filesize). * 072 21-Jun-91 tmk Check (and prohibit) spawns from captive accounts. * 073 21-Jun-91 tmk Fix session logging (for Charlie Luce/DECUServe). * 074 21-Jun-91 tmk Rework 071 to only apply to SPAWN/PUSH and not to the * pseudo-builtins like DEL, SPACE, WHO, PWD, etc. * 075 21-Jun-91 tmk Fix possible endless loop when flushing output file in * 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* * fixed-format files be sent as text). * 083 15-Jul-92 jah Fix fencepost error in zoutdump when line breaks at 32K. * 084 03-Aug-92 fdc Remove current directory from init file search. * 085 26-Aug-92 tmk Add Bernd Onasch's fix for fgen(). * 086 28-Aug-92 tmk Fix bug reported by Bill Hoelzer where C-K would execute * a file named "." as a C-K initialization file. * 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.

Vote for Kermit! * 093 03-Nov-92 fdc Change zkermini() to work with "-y" command-line option. * 094 04-Nov-92 tmk Make zxpand() not return all files if given null string. * 095 05-Nov-92 fdc Make zxcmd(), zclose(), etc, handle ZRFILE (OPEN !READ). * 096 17-Feb-93 fdc prevent zopeno from calling zstime if date struct is NULL, * and add support for ZMFILE (misc output file). * 097 08-Apr-93 tmk Correctly handle "international VMS" which uses <> instead * of [] for directory delimiters. * 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 * quieten the compiler (which had every reason to complain). * 103 5-Nov-93 wb Add isdir() function. * 104 8-Nov-93 wb Add zfcdate() function. * 105 25-Nov-93 fdc Correct record format for session log; change name of * password structure member of zattr struct. * 106 22-Dec-93 tmk Correct fd "leakage" in OPEN READ/CLOSE READ pairs. * 107 26-Feb-94 mb Addition of zmkdir() routine. * 108 27-Mar-94 tmk Increase max record size for logs from 80 to 254. * Add support for file append operations. * 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.

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.
