thanks bitRAKE, but it doesnt seem to do the same than ror/rol
i cant use those strucs in my macro (error extra characters on line) so i did this: _char = ((_char shr 3) + (_char shl (32-3))) and 0xFF but the result is different than using ror/rol :S |

Need to add more masking to clamp values? I didn't test it, but the general idea is sound. If you are only working with characters then it would be:
_char = ((_char shr 3) + (_char shl (8-3))) and 0xFF The size of the values being operated on is important. _________________ ¯\(°_o)/¯ “languages are not safe - uses can be” Bjarne Stroustrup |
