Author McGath writes: “Wait one widgeting minute! It is not necessary to tinker with the economics of Widget to make it winnable; just correct one typo: 600 should be

LET S=S+B*8

This vastly improves the return on small advertising outlays as was originally intended. The other tinkering can still be done to vary the challenge of the game, but a conservative strategy will result in steady growth. I hope the error in Widget has not shaken anyone’s confidence in the free market too badly.”

A Trick and a Graphic System (1:3, pp. 30-31)

Author Comer calls attention to the continual problem of making a distinction between zero and the letter O. Since this is not clear in the listing, he suggests: “In order to get the examples to run all one need realize is that everything is an Oh. The only exception is in the example called the ‘U.S. Map.’ At the end of the second line the data should be “eleven Oh twelve.” Otherwise the map data is correct, but pay close attention to the zeros (which are narrow) and the Ohs (which are wider).”

Add:

9010 REM ENTER FROM POLYGON/SEGM
ENT/ARC

Correct:

9920 IF P2>2*PI THEN LET P2=P2-2
*PI*INT (P2/(2*PI))
9925 IF T2>2*PI THEN LET T2=T2-2
