Thanks for finding this. nil is only allowed in ++, --, inc and dec when contents of a variable, else it is seen as a wrong parameter.

fixed here: http://www.newlisp.org/downloads/develo ... nprogress/

I'd say Bug!

Apparently ++ manages to increment nil so now the value of nil is 1.
It also appears to require a compound set of circumstances for allowing ++ increment nil, so: Well done, for finding this problem.

EDIT: Lutz was already well ahead (of course?).
