Therow of automobilesin the nextprinted lineiscreated bydownloading

two newcharacter patterns, which are printed in place of the character”<”

(character 60). Details can be found in Appendix C.

The final part of the program usesdot graphics to print an “S&S”logo.

The dot pattern of the logo was originally laid out on graph paper, then

converted to the data in lines 2640 to 3030 with the help of a calculator.

Each number represents eight vertical dots. (See “Graphics commands” in

Appendix B for details. See also Figure C-1 in Appendix C.)

The pattern is printed in four rows, each eight dots high and 100dots

wide.Lines 1800to 1850read the dot data into a stringarray variablenamed

LOGO$. Line 1860sets

thelinespa@gto8/72 inch so that the rows will

connect vertically.The loop in lines 1870to 1940does the printing in four

passes of the print head.

This program can also be run in IBM mode (DIP switch 1-6 OFF) if

you change a fewof the linesas shownbelowto allow for differencein some

of the commands. You will get a cylinderinstead of a barrel effect, becuase

the IBM mode does not have any command to micro-adjust the character

spacing.
