Issue: RAdio:BINFIfo always returns Data Tyep Error

I tried some method to test RAdio:BINFIfo as following:

RAdio:BINFIfo "hello"
**ERROR: -104, "Data type error"
RAdio:BINFIfo #H1234
**ERROR: -104, "Data type error"
RAdio:BINFIfo #B10101111
**ERROR: -104, "Data type error"
RAdio:BINFIfo #H12 #H34
**ERROR: -101, "Invalid character"
**ERROR: -113, "Undefined header"

It seems there is no valid format at all. I will try be best to debug the lexer later.
