Macro syntax for non-negativity

Question

Hi,
Could some one copy past the syntax for non-negativity like this
If KF1 < 0, then KF1 = 0 else KF1
This condition needs to be applied on top of existing macro for KF1 that does some arithmatic whose result could be < 0.
would appreciate if you copy paste the steps.. that you may already have in any of your macro books.
I also take this opportunity to request the macro experts to compile a wiki document on macro syntax.. A piecemeal approach would also do without relating to WHERE such a macro could be used. I find this learning the macro syntax by trial and error a rather unproductive and painful experience.
If some of you could volunteer lets build a fantastic reference document on the macros where everyone can contribute and come with with something really useful.
The final list can then be classified into artithmatical, conditional, control, abap macros. A brief description alongside each macro and some expert comments on possible application can be later expanded. newer and alternate ways of realzing the same macro creatively and in lesser steps could be regularly appended. I could moderate if such a thing is correct and agreeable
