Re: another problem [was: if-expression in equation section]

[dieter]

Sorry, my problem has nothing to do with if-expressions I think my
problem is that I have initiated (in the protected section) variables
with the same name because I thought they were truly local to the
class.  Is there a possibility to specify local variable in OM?

Thanks
