The vr3a application displays text files on the s3a in Vertical orientation.
 
It is a type $9003 application for the Series 3a only, it uses
files with a .TXT extension in VR directory, multiple files can be opened
but new files cannot be created. Text is displayed in one of eight fonts
with a choice of mono- or proportional spacing. Lines which are too wide
for the display can be truncated or wrapped according to preference.
The current position in a file, along with font and display mode
information, is automatically retained between invocations. The reader can
advance through the file a line at a time or a page at a time, jump to a
specified line or search for a line contining a specified text string.
