A naked expression is not a legal PL/M statement. You meant: a = b + a; > if (a := b) .. /* OOPS, I only wanted to compare them */ I think that is only legal is a and b are booleans. In any case, you want: if (a = b) .. Back to the point. If I was god and got to fix C, I'd make the indirection operator postfix before playing with assignment and equality. -- Peter da Silva. `-_-' +1 713 274 5180. 'U` <peter@ficc.ferranti.com>
