This is a package of 10 subroutines for an 8K FORTRAN
system (OS/8, PS/8, or paper tape) which allows any FOR-
TRAN or SABR program to display graphical figures or text on
a VT01 storage tube. Provision is provided for erasing the
screen, turning on or off the cursor, testing the cursor flag,
reading cursor coordinates, and drawing points, lines and
circular arcs. Text strings may also be displayed anywhere on
the screen with characters of arbitrary width, height and
orientation. Any of the 64 printable ANSCII characters may
be drawn. Core required is 8 pages.
