I think so Juergen. I understand you to say that by adopting your routine
we will have a "standard" way of declaring a variable of type boolean (which
is already inherent in some other languages, eg Java) and ensuring the 
validity of a value we assign to it; and this would make our programs easier
to read and more logically consistent (ie "boolean" implies true/false, 
whereas "integer" or "constant" can mean other things as well). Yes?

I hadn't thought of doing that. I've been using:

constant FALSE = 0
   constant TRUE = 1

and assigning those values - eg setFlag = TRUE

I understand the basics of using variables as flags (but am pretty shakey
on using bits for this purpose).

And I thank you for the particular example you used - I didn't know how to
break out of nested loops using exit!
