or if possible doctor the patient ?
It may have to be constructed recursive style

Thanks in advance ... Jean

Here's something that at least evaluates on 0.99.7030. One thing to note about your function.
There isn't a "return" statement in Smath programming. A program returns the last line entry by default. So to compensate, you have to assign values to a variable and pass that variable at the end. In this case I chose "ans".

I also used "cases" function to clean things up a bit.

I had an error some of the logic. Also updated to mimic graph that was attached.
