hi,
I want to show magnetos status at lcd display.
when I use below formula in transform field it's working. But second formula with text (OFF, RIGHT etc) is not working. Expression syntax page says "Strings are also possible" and gives third formula. so is this a bug?

if($=0,0,if($=1,1,if($=2,2,if($=3,3,if($=4,4,999)))))

if($=0,'OFF',if($=1,'RIGHT',if($=2,'LEFT',if($=3,'BOTH',if($=4,'START',999)))))

If a value is greater than 10000 then 1 else 0
if($>10000,1,0)
Strings are also possible
if($<=10000, ‘LL_ON’,’LL_OFF’)

Hi.

Your on the right way.... But on the wrong spot.

At first....
I hope the first Line

if($=0,0,if($=1,1,if($=2,2,if($=3,3,if($=4,4,999)))))

was just a example.... Cause its way to difficult .... 0=0...1=1....2=2....3=3....4=4 ... All else is 999
here if($<5,$,999) do the same.

About String Problem....

In TRANSFORM we currently not allow String Entrys . Its still conflicting with the internal "handoff" of this value to the later elements like Compare, Interpolation and also e.g. a Motor.
A Transform always execute a Integer .... So result can not be a String. Floats are truncate to integers also.

Solution:
In COMPARE Strings are allowed.... Simply use your code line in the Compare Tab.
E.g. in the THEN field.... And in the IF you define something that is always true.... E.g. IF Value >=0
So the THEN will be executed at all time ..... And do what you need .... if($=0,'OFF',if($=1,'RIGHT',if($=2,'LEFT',if($=3,'BOTH',if($=4,'START',999)))))

thank you problem solved

and yes, first line was an example for testing purpose.
