Program: VREN (Visual RENamer)
Author: Bruce Morgen	(contact via DHN* @ 215-623-4040 or
Version: 1.0		 Lillipute Z-Node @ 312-649-1730)
Date: August 8, 1988
Purpose:
	Interactive renaming of files with format checking.
	VREN takes a single wildcard filespec from the command
	(if none given, "*.*" assumed).  It then allows the
	user to step through the file names and change them
	using the WordStar(tm) diamond and/or the TCAP-defined
	arrow keys for cursor movement.  This includes the WS
	control-A/control-F end-of-line commands.  VREN always
	operates in an overwrite mode - there is no control-V
	mode toggle.  Typing a period (.) moves the cursor to
	the first character of the file extension, wiping out
	any remaining filename characters to properly
	attributed blanks, unless the cursor is over the first
	character of the extension, in which case it moves to
	the last character of the filename.  Otherwise editing
	behavior is quite predictable.  There is a rubout
	function closely resembling WS response and the WS
	control-G (gobble) also works, although both treat the
	filename and extension as distinct fields.  A carriage
	return initiates the actual renaming of the file.  VREN
	toggles file attributes using control-T as the trigger,
	but, as with a rename, nothing changes until a RET.
	Any attributed characters are shown in alternate video
	or lower case if possible.  Unless VREN is "quieted"
	there is a "12345678|rsa" header for clarity.  There
	is protection against setting attribute #2, the home
	of the Plu*Perfect-style "PUBlic" tag, if more than
	one file of the name in question exist on the same
	drive.  To disable this feature for non-PUBlic BDOS
	or vanilla ZRDOS, see "Patching" below.
_______________________________________________________________
	
	Patching: VREN obeys the ZCPR3 Quiet Flag unless the
	low (0) bit of the byte at origin+2 (102h in DDT) is
	patched to a non-zero value - in that case VREN is
	always "quiet."  The high (7) bit of this byte
	controls the attribute #2 protection scheme for
	Plu*Perfect-compatible DOSs described above.  Set
	this bit if you know what you're doing and want to be
	able to set attribute #2 at will.

	Value at origin+2		Results in:
	-----------------		-----------
		00h		"loud" & PUBlic protected
		01h		"quiet" & PUBlic protected
		80h		"loud" & PUBlic unprotected
		81h		"quiet" & PUBlic unprotected
