I don't know if it works but.......

B4X:

Dim bit0, bit1, bit2 as boolean
Dim mybyte as byte
bit0 = Bit.And(mybyte, 1) 'Get bit 0 in byte
bit1 = Bit.And(mybyte, 2) 'Get bit 1 in byte
bit2 = Bit.And(mybyte, 4) 'Get bit 2 in byte
.... and so on

Thanks Sergio,
Getting close to the simplicity I'm used to but to set the value?

To set a bit use OR.

From example above

B4X:

mbyte = Bit.Or(mbyte, 4) 'sets bit 2

But Erel's SetBit function showed on first link in post#2 is better and of more general use.
