repeat for each char c in negated_binary_file
put charToNum(c) into x
put numToChar(255-x) after fixed_binary_file
end repeat

Hi,

i have here some binary files, which were negated bitwise. How can i "convert" them back?
Is there a livecode function i can use?

Or do i have to 
convert the binary file to hex, 
convert each byte to decimal,
convert each "decimal"byte value  with "bitNot",
reconvert to hex and then convert to binary again?

Any ideas?

Regards,

Matthias
