Am I doing something wrong or is this a firmware bug? I'm on 5.07.00b19 thanks!

The normal use is for writing binary to and from a file or for converting a string containing binary values such as received from some I2C devices into a MMBasic number. For your usage you need to look at functions like VAL and BIN$
