LogMessage : ** -*- changed on Donnerstag, 12.01.95 13:26:43 by Kai Iske. LogMessage : ** - Changed version numbering to official scheme ** -*- changed on Mittwoch, 11.01.95 11:04:23 by Kai Iske. LogMessage : ** - One couldn`t move the entire contents of a directory ** to a dir within that directory (eg. Move #? Dummy) ** -*- changed on Mittwoch, 11.01.95 11:03:55 by Kai Iske. LogMessage : ** - One couldn`t move directories, if the destination dirs ** already existed (eg. Move Dummy1 Dummy2 t:; if Dummy1 ** and Dummy2 both existed in t:) ** -*- changed on Montag, 05.09.94 23:16:13 by Kai Iske. LogMessage : ** - OldWindow and HitMask vars weren`t preset to 0 ** (Reported by : Christian Buchner) ** -*- created on Monday, 30.05.94 09:20:04 by Kai Iske. LogMessage : ** - When one issued something like this "Move #? dummy/", ** Move stopped when trying to move dummy to itself ;) Fixed ** ** Revision V1.10 ** -------------- ** created on Sunday, 06.03.94 16:57:29 by Kai Iske. LogMessage : ** -*- created on Sunday, 06.03.94 16:57:29 by Kai Iske. LogMessage : ** - Move didn`t end up some operations with a "moved" string, ** thus leading to corrupted display ** (Reported by : Albert-Jan Brouwer) ** - One still couldn`t rename a directory ** (Reported by : Albert-Jan Brouwer) ** ** Revision V1.9 ** -------------- ** created on Saturday, 26.02.94 14:15:24 by Kai Iske. LogMessage : ** -*- changed on Saturday, 26.02.94 14:29:20 by Kai Iske. LogMessage : ** - On recursive moves, Move will indent the output according to ** recursion depth. This is for better readability ** -*- changed on Saturday, 26.02.94 14:19:22 by Kai Iske. LogMessage : ** - Move will refuse to move a dir to itself now. ** -*- created on Saturday, 26.02.94 14:15:24 by Kai Iske. LogMessage : ** - One couldn`t move a dir to another dir on the same device ** ** Revision V1.8 ** -------------- ** created on Sunday, 19.12.93 01:44:05 by Kai Iske. LogMessage : ** -*- changed on Sunday, 19.12.93 01:47:54 by Kai Iske. LogMessage : ** - Added PURE information to Doc, since Move really is pure ** (Suggested by : Albert-Jan Brouver) ** -*- changed on Sunday, 19.12.93 01:46:23 by Kai Iske. LogMessage : ** - Due to the move-renaming bug one couldn`t rename a dir ** an Assign was put on. ** (Reported by : Albert-Jan Brouver) ** -*- created on Sunday, 19.12.93 01:44:05 by Kai Iske. LogMessage : ** - Fixed move-renaming of directories. ** (Reported by : Albert-Jan Brouver) ** - Move had some severe problems recursively moving ** the contents of a directory ** ** Revision V1.7 ** -------------- ** created on Saturday, 04.12.93 23:19:03 by Kai Iske. LogMessage : ** -*- changed on Saturday, 04.12.93 23:26:25 by Kai Iske. LogMessage : ** - Error while moving to a "device full" disk ** (Reported by : Chris Conger) ** -*- created on Saturday, 04.12.93 23:19:03 by Kai Iske. LogMessage : ** - FileName length-bug fixed ** (Reported by : Juergen Lang) ** - Recompiled using SAS 6.50 ** - Stack usage reduced ** ** Revision V1.6 ** -------------- ** created on Friday, 15.10.93 15:51:13 by Kai Iske. LogMessage : ** -*- changed on Saturday, 16.10.93 15:17:29 by Kai Iske. LogMessage : ** - Move got screwed up, when attempting to move a ** zero size file ** -*- changed on Friday, 15.10.93 16:03:35 by Kai Iske. LogMessage : ** - Added Buffer Keyword to specify the maximum buffer ** size for an inter device move. Normally Move would have used ** the max amount of available free memory in order to ** accomplish the move, or the size needed by the file... ** (Suggested by : Christof Damian) ** -*- created on Friday, 15.10.93 15:51:13 by Kai Iske. LogMessage : ** - One couldn`t rename a file using move, because the ** "destination" file was removed before doing the rename, ** ie. the source file was deleted. ** (Reported by : Chris Conger) ** ** Revision V1.5 ** -------------- ** created on Tuesday, 05.10.93 01:42:53 by Kai Iske. LogMessage : ** -*- changed on Tuesday, 05.10.93 02:03:22 by Kai Iske. LogMessage : ** - Freed the FileInfoBlock _BEFORE_ setting the Bits, Comment ** etc. This lead to MungWall hits (of course it did) ** (Reported by Nico Francois) ** -*- created on Tuesday, 05.10.93 01:42:53 by Kai Iske. LogMessage : ** - Exidentially called one ExAll() without ED_SIZE ** This lead to some calls to DoTheMove without the Size set ;) ** (Reported by Karsten Weiss) ** ** Revision V1.4 ** -------------- ** created on Friday, 01.10.93 16:55:15 by Kai Iske. LogMessage : ** -*- created on Friday, 01.10.93 16:55:15 by Kai Iske. LogMessage : ** - Now uses Rename() when source and dest are on the same ** device. This is faster ;) Why haven`t I thought of that ** earlier ??? ;) ** ** Revision V1.3 ** -------------- ** created on Wednesday, 25.08.93 16:32:43 by Kai Iske. LogMessage : ** - UnLock Problem solved when doing recursive Dir-Moves ** This bug lead to "Object in use" error messages ** ** Revision V1.2 ** -------------- ** created on Tuesday, 17.08.93 22:48:38 by Kai Iske. LogMessage : ** - Added CTRL-C checking ** - Added FORCE Flag in order to move read/deleteprotected or ** to overwrite a delete/writeprotected files ** ** Revision V1.1 ** -------------- ** created on Monday, 16.08.93 22:53:34 by Kai Iske. LogMessage : ** - Added well known CLONE, DATES, COM, NOPRO, ** QUIET and NOREQ options also used by e.g. Rename ** ** Revision V1.0 ** -------------- ** created on Wednesday, 11.08.93 15:01:14 by Kai Iske.
