This is a subroutine requiring exactly one page (128 words) of

memory. Its purpose is to draw a linear vector from any point

on an oscilloscope display to any other point. There are 5

arguments in the subroutine calling sequence which specify

the starting point (X₁, Y₁), the ending point (X₂, Y₂) and

a stepsize. The stepsize (range l to 7) determines the point

density along the vector.

The ASCII tapes which are offered are with or without com-

ments. Please specify which tape you wish. The binary tape

is a program which demonstrates the use of the oscilloscope

Vector Generator Subroutine.
