Hi Jarek, I've been able to use a single remembered output ie LastOut scenario like this:
In4==0? In1 : Out1+(Out1*(In2-In3)/1000)
But if I define Out1 first with Out1=... then I lose the ability to do the above, which means that I can't really implement a LastIn feature. Is there any known workaround, or do I need to use the Delay element?
Thanks kindly, Stepan

1. It is possible to use LastInX variable to get the last input value.

2. I don't quite understand what you are trying to do. If you don't add \"Out1=...\" in the expression, then it is added there later automatically, so I don't see how it changes anything.

3. It is possible to use higher output variables which are not connected, for example:
Out3=Out1+(Out1*(In2-In3)/1000); Out1=In4==0? In1 : Out3;

Now that's handy =) Order of precedence was messing me up.

Look... this expression uses remembered Out1 in the first half:
Out2=Out1+2;Out1=In1
But this one does not because the first section overwrites Out1:
Out1=In1;Out2=Out1+2
But we can save Out1 into Out3 before executing the expression:
Out3=Out1;Out1=Out1+2;Out2=Out3*2

Is order of precedence guaranteed to be left to right?

I used to think that everything was possible in Bioera and that everything was difficult.
Now I know that the impossible is still difficult in BioEra, but BioEra is(does) everything!

Yes, order is guaranteed from left to right for expressions separated by semicolons.
