PureBasic Forums - English

Anyone know if there are any beginners tutorials for assembly language on the mac
using Purebasic?

Thanks

Have you already looked at the assembly forum ?

If you don't need any api calls, there's not much difference compared to assembly language on Windows or Linux.
Maybe a bigger difference is between x86 and x64.
