Notice that variable A12 is no longer there.   If you now press „§, the 
screen will show the contents of sub-directory MANS, including variable A12:

Variables can be deleted using function PURGE.  This function can be accessed 
directly by using the TOOLS menu (I), or by using the FILES menu  
„¡

@@OK@@ .

Using the FILES command
The FILES command can be used to purge one variable at a time.  To delete a 
variable from a given directory you can use the FILES menu. For example, within 
the sub-directory {HOME MANS INTRO}, we have variables p1, z1, R, Q, 

α,

and A left.  Suppose that we delete variable A.  Here is how to do it:  Press 
„¡

@@OK@@ to produce the variable list.  Use the down-arrow key ˜ to 

select variable A (the last in the list), then press L

@PURGE@ @@@YES@@@.   The screen 

will now show the contents of sub-directory INTRO without variable A. 

Using function PURGE in the stack in Algebraic mode
We start again at subdirectory {HOME MANS INTRO} containing now only 
variables p1, z1, Q, R, and

α.  We will use command PURGE to delete 

Note: You can use the stack to move a variable by combining copying with
deleting a variable.  Procedures for deleting variables are demonstrated in
the next section.
