DECUS Essential Tools Collection, 1996 for OpenVMS Alpha and OpenVMS VAX (VS0174)

This utility will delete the specified directory tree (i.e., all files
and subdirectories in the specified directory and then delete the
directory itself.)

Requirements:
VMS operating system

Optional:
VAX BASIC V3.x - Only if you wish to modify or rebuild. The executable
                 on this distribution was built under VMS V5.5.2 using
                 VAX BASIC V3.5.

Files included in this distribution:
AAAREADME.TXT		- This file
DELTREE.ALPHA_EXE	- VESTed executable image Alpha
DELTREE.BAS		- Source code
DELTREE.CLD		- Command language definition file
DELTREE.EXE		- The executable image
DELTREE.MMS		- MMS makefile
DELTREE.COM		- Build procedure for those that don't have MMS
DELTREE.OBJ		- Object from DELTREE.BAS
DELTREECLD.OBJ  	- Object from DELTREE.CLD

Build instructions:
$ basic deltree
$ set command/object=deltreecld deltree
$ link/notrace deltree,deltreecld
$ deltree == "$disk:[directory]deltree"

The command:
$ deltree [foo.bar.tmp]

Will delete everything in [foo.bar.tmp] up to and including
[foo.bar]tmp.dir itself. This assumes you are executing the command from
an account with enough privileges to delete all the files and directories or
that you have set the protection on the files so that you can delete them.

The /LOG qualifier when present will cause deltree to print progress
messages to sys$output. For example:
$ deltree/log user:[foo.x]
%DELTREE-I-FILEDEL, USER:[FOO.X]TEST.TXT;1 deleted (1 block)
%DELTREE-I-FILEDEL, USER:[FOO.X.Y]Z.DIR;1 deleted (1 block)
%DELTREE-I-FILEDEL, USER:[FOO.X]Y.DIR;1 deleted (1 block)
%DELTREE-I-FILEDEL, USER:[FOO]X.DIR;1 deleted (1 block)
%DELTREE-I-TOTAL, 4 files deleted (4 blocks)

Of course you will to have delete access to all the files and
directories that you intend to delete or else run it with sufficient
privileges.

I wrote this utility to correct a couple of bugs and to enhance the
logging and error messaging of a similar utility. Differences include:
	o Fixed bug that caused an access violation.
	  This only occured when deleting a file that had an
	  extension that started with DIR but was longer than 3
          characters. Such as PHONE.DIRECTORY. This bug also showed
	  up when trying to delete a subdirectory whose file name 
	  started with the letters DIR.
	o Fixed bug that said a file was deleted even when it wasn't
	  when using the /LOG qualifier.
	o Invoked as a foriegn command. No more abbreviation conflicts
	  with the DCL DELETE command!
	o /LOG qualifier logs each file deleted and not just the last one.
	o Log messages include the file size in blocks.
	o Total files and blocks deleted is reported when /LOG is used.
	o Greatly enhanced the error messaging in general.
