Title: FOR-NEXT with negative increment
Post by: Controls Guy on May 21, 2019, 02:18:50 PM

I could have sworn I've done a FOR-NEXT with a negative increment value, but DMD won't allow it.  Am I having a senior moment?  Even if so, is it feasible to make negative increments happen?

Host probably wanted to keep things positive, none of this negativity.

It kept the implementation cleaner. And because we are mean.

I knew it!  However, you fail at meanness, because typically a FOR is for an index and since 90% of my output instructions are MATH boxes, where you let us do expression indexes anyway....it's all good!
