brainfuck interpreter

hello, thanks for reading my topic. i am writing a brainfuck interpreter for my os. Actually it is very easy but i'm having problems with loops:

[ Jump forward past the matching ] if the byte at the pointer is zero.
] Jump backward to the matching [ unless the byte at the pointer is zero.

Do you have any idea about how can i code those instructions?

thanks

It depends on how the rest of the interpreter works.

You can take a look at DexOS's brainfuck interpeter, if you want.

dex, is it possible to put a loop into another loop in your interpreter?

I did not code it, it was a member of Team DexOS called Solidus117.
But depending where in the loop and as long as it does not slow it, or change a needed reg etc.
You should be OK, but if in doubt, try it.
