Yes.  Revolution can be used to process any arbitrary binary file.  (Of  
course, it is faster at some things than others.)

A binary file can be considered a sequence of bytes.  Each byte  
corresponds to a character in Revolution.  Use charToNum() to get the  
numerical value.  Use numToChar to go the other way.  These are basic  
and reliable.

That is all that is really needed, but Revolution provides more:   
binaryDecode, binaryEncode, baseConvert, bitAnd, bitOr, bitXor, bitNot.
