readInteger(address) & (1 << bitnumber)

e.g
readInteger("Example.exe+ABC123") & (1 << 0)

or tonumber(AddressList.getMemoryRecordByDescription('test').Value)

i just want to confirm

the 1 in (1 << 0) is the "BitLength"
and
the 0 in (1 << 0) is the "BitStart"

right?

half. the 1 is a bitmask. if you want a longer bitlength you will have to calculate a bitmask. Easiest is mask=(1<<bitcount)-1

so if you want to use multiple bits then the formula is:
readInteger(address) & (((1<<BitLength)-1) << BitStart)
