** File : SnakeSYS:CPrgs/Utils/Move.c
** Created on : Wednesday, 11.08.93 15:01:14
** Created by : Kai Iske
** Current revision : V37.11
**
**
** Purpose
** -------
** - Small move utility which supports wildcards and doesn`t use
** Rename() nor Copy() nor anything similar...
**
** Revision V37.11
** ---------------
** created on Monday, 30.05.94 09:20:04 by Kai Iske. 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
