SPECTRUM PLOTTER



Save time and graph paper with this splendid program

written by David Elphick of Bristol.





This program has been written for Spectrum owners who

frequently make use of user defined graphics within their

listings. The graphic is first plotted eight times the

normal size on a grid 16 squares high by 32 squares wide. A

cursor (*) is moved around the grid using the direction keys

on the Spectrum - the '5', '6', '7' and '8' keys - which

will move the cursor left, down, up and right respectively.

If you would like to ink in a particular square, simply

press CapsShift and the '5', '6', '7'or '8' key.



Once you have defined the graphic you wish to use in a

program, you simply press the 'G' key to provide the normal

size graphic. If this process takes a couple of seconds,

don't panic!



If you're not happy with the shape of the graphic, you can

change it by pressing the 'C' key and making the necessary

alterations. Pressing the 'L' key provides a list of the

decimal codes for each of the eight graphics characters.
