The CAPS command changes
the case for text not yet entered, or for text that is modified in
a window. If you specify CAPS ON and enter text, the text is changed
to uppercase as soon as you press ENTER or RETURN. The setting remains
in effect for a window until the SAS session ends, or until the setting
is changed by another CAPS command. You can use the WSAVE command
to save the setting of the CAPS command beyond your current SAS session.
