PR

PR is a replacement for the CP/M utility TYPE. It simply displays
on the CRT the file referenced. Usage is simply

     PR <filename>

In this case,  wildcards and file lists don't make much sense and
are  not supported.  The key thing about PR is its flow  control.
Unlike virtually every other file display program,  it does _NOT_
stop  at  the  end  of 24 lines and ask you to	press  a  key  to
continue.  Nor	does  it use CP/M's ^S/^Q flow control (I am  the
president,  founder,  and  only member of the Society to Ban  the
Control Key).

Instead,  I  use a scheme I had gotten used to on other  systems,
and  learned  to like.	The SPACE BAR halts  scrolling,  and  the
CARRIAGE  RETURN resumes it again.  I know,  this seems a  little
wierd  at  first,  but it's easy to get used to and  seems  quite
natural after awhile.

The nice thing about this, aside from the fact that the space bar
is big and easy to find in a hurry,  is that it also serves as	a
"single-step" key.  After stopping the scroll with the space bar,
hit it again to scroll one line, and again for the next, etc. Hit
the RETURN key at any time to resume.

If  you've  seen  enough,  an (ugh!) ^C terminates  the  program.
However, this only happens if the scrolling has been halted.

Unfortunately,	because of the way I implement raw character  I/O
in  C,	the  CP/M  ^P key to send the file to the  printer  isn't
supported.  If you want to redirect output to the printer, you'll
still have to use TYPE. Sorry.
