The "I" in the line

> binary scan [binary format I $hexa] B* binStr

means "32-bit integer". When $hexa is a larger number than can be
represented in 32 bits, [binary format] can't do the job you've asked
it to do.

If you need to be able to convert numbers of arbitrary size, take a
look at this wiki page, which provides some generalized procedures for
converting integers into base-2 strings:
