Are you converting an ASCII representation of a binary number (i.e., 01000111000) or are you looking for the binary values of the ASCII characters?

OK. If I understand correctly maybe this will help.
Let's start with a string: 01000101 (hex 45)
% set as 01000101
01000101
% set bs [binary format B8 $as]
E
