I have some questions.
Please give me info.

1: When I use "append" command as such situation below..

	monitor -TN -c "append ***** " dbname
	or
	monitor -TN -c " ***** " dbname

	Any method for inserting the filename or script in ***** ?

2: How to add/delete the attribute from the class?
	If can't, I have only way [remodify the class] ?
	so,how to copy the data in attribute ? > question 3		

3: When I add the new attribute in the class,
	Any method for copy the old attribute data 
	to the new"same"attribute ?
	for example..

   [old]	class   |  attribute (data)
   -------------------------------------------
		EMP	| name = "Joe","Sam","Bill"
			| salary = 1000,2000

   [new]	class	|  attribute (data)
   -------------------------------------------
		EMP	| name = ""
			| salary = ""
			| age = ""	/* new added attribute */

	The data in old attribute(name,salary) move in
	new "same name" attribute, HOW?
