Variable names

In ThingsPlex string variables can have names as per following rules …

fh.mode.string using . to make names readable.

But float variables fail if you use . ?

So for Float and integer you can use _ ?

Any documentation on variable names syntax somewhere ?

To be on safe side , I now only use Cap MyExtraBigFloat .

Is it really so? I always only used underscore, haven’t had any issues as far as I can tell…

Gets a strange cannot convert to float error , when using variables .
