Adding and reading byte variable from the bit array?

[richard]

As I understand, such operation is not possible in PBP, I mean, it is not possible to substitute variable as a bit part identifier for another variable?

where did you get that idea, it is very possible with the correct syntax

suggest a read of the manual re

Applying Offsets to Bits within a Variable or Register

I didn't get the idea, I just tried it and it gives syntax error......
