Tandy 1000 User Manual

Basic
The SCREEN option tells BASIC to set the coordinates similar to
the screen display in that the lesser y-coordinate is in the upper-left
corner of the screen. If you omit SCREEN, BASIC inverts the
y-coordinates to show a true Cartesian coordinate system. That is,
the lesser y-coordinate
is in the lower-left corner of the screen.
WINDOW lets you plot points outside the normal screen coordinate
limits by setting new world coordinates to the screen.
WINDOW (1 984,100000)-(1987,300000)
WRITE data[,data,. ..I

WRITE D, B, V$
WRITE#buffer, data[,data, ...I
