lookup

[reynolja]

How do I reference a text from a number reference?  I wan to call fro example B0 and see "start bit"

B0	START BIT
B1	PACKET LENGTH
B2	PACKET ID
B3	OCU A ADDRESS HIGH BIT
B4	OCU A ADDRESS HIGH BIT
B5.0 - 5.1	OCU A DIRECTION
B5.2 - 5.4	OCU A AUTO BRAKE OVERRIDE
B5.5 - 5.7	UNDEFINED
6.0 - 6.2	OCU A INDEPENDENT BRAKE OVER RIDE

There are many ways to do this. How big are the tables?

What's the meaning of "B" That does not sound like a number, especially since some have decimal points. It seems you probably want to strip the B. What should be returned for non-existent values (e.g.5.9)? Are thre other letters besides a leading B?

You could create a numeric array of boundaries, then use "threshold array" to get an result (rounded down or up) to be used to index into an array of corresponding texts. (you could modify this example)

Here are several posts using Variants as look up tables where you have a name and value pair.

I am not quite sure how you would implement the ranges using variant attributes. In this case there could be an infinite number of names (e.g. B5.2 .....B5.4) for a certain atttribute (OCU A AUTO BRAKE OVERRIDE).
