On 87 I have to made a choice so the user can choose between a
Vcat and a VCham so one animal and one gauge.<br>
I have then to think how I can prevent that whn the user chooses a
Vcham petting does not work. <br>
<br>
<br>
Thanks for the help.<br>

I meant exercise 87 and 88 on the stable version of HtpD/2e.<br>
<br>
So the questions I have should be :<br>
<br>
Is it correct that on exercise 87 of How to design Programms I
have to make 2 gauges and two animals.<br>
And is exercise 88 part 1 not the same as exercise 56 ?<br>
