						USS Help File

This file contains information about the USS Digital Recording Studio.

USS manual.  The purpose of this file is to provide an on line help
utility for the USS user.  Upon the press of the F1 key, a screen will
pop up and topics will be displayed.  Those topics which are displayed
are the text following the "TOPIC" keyword placed at the beginning of
any line.  When the mouse clicks on any of the displayed topics, the
text after the topic and before the next topic will be displayed on the
screen.  PageUp and PageDn are supplied for topics longer than the display
length.  Lines longer than 42 characters will character wrap to the next line.
The display screen can fit only 21 lines of text.  The display will only
print alpha-numeric characters(0-9,a-z,A-Z).  Characters such as TAB will not
be printed.

This is the first help topic...
