ahh i see
thanks
going a = a $(0x1 << 6) reverts back then again I could just initialise it
again to default :) tks guys

you're binary-or'ing a bit with 0x0, which means you're not going to change
it.
There's some useful information
here: https://en.wikipedia.org/wiki/Bit_manipulation

I find bits(a) more useful than bin(a). It enables me to see all the bits
of an integer when experimenting with << and >> to see if I'm doing the
right thing. eg, set the 2nd bit of a byte:
*julia> **a = 0b0010*
*0x02*
*julia> **bits(a)*
*"0010"*
*julia> **a = a | (0x1 << 6)*
*0x
