This is the pager program Less for OS-9000. Less is similar to more, but
there is more to less, so to speak.

To install, copy the binary file Less to your favorite CMDS directory and
copy the file less.help to your /dd/SYS directory. Set the file access
attributes how you want them. Any user which you wish to grant access
to less must have execute access to Less and read access to less.help.

To use:

$ less filename

Once in less, enter an "h" to display the help file. (Less is simply
called in a subprocess to display the help file.)

If you have set the screen colors to something other than the default
white on black, you can tell Less this by using two special environment
variables. For example, if you prefer a white foreground on a blue
background, include the following in your .login procedure file:

setenv FOREGROUND WHITE
setenv BACKGROUND BLUE

Valid foreground colors are BLACK, RED, GREEN, BROWN, BLUE, MAGENTA,
CYAN, WHITE, GRAY, BRRED, BRGREEN, YELLOW, BRBLUE, BRMAGENTA, BRCYAN,
& BRWHITE.

A color name which begins with "BR" is a bright color, ie, BRRED is
Bright Red.

Valid background colors are BLACK, RED, GREEN, BROWN, BLUE, MAGENTA,
CYAN, & WHITE.

Oh yeah, one more important thing. You will need to edit your OS-9000
system's /dd/SYS/termcap file and remove the entry for "al" in the
definition of the "pcat" terminal. Make sure there is no entry for "sr"
either. Both functions appear to be braindead in OS-9000's ANSI terminal
emulation. Without either of these defined you will get a warning
each time you less a file which states that your terminal cannot
scroll backward, but you can still go backwards in a file, either a
page at the time or a line at the time. It will just repaint the entire
screen starting at the place you request. On my 80386DX/33, this is
so fast, I hardly see it.

Enjoy!
