Deleting variables

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, ,

„¡@@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

variables p1, z1, Q, R, and . We will use command PURGE to delete
