Hello, Does anyone know a way to insert pure assembler code into HiTech C Compiler ? I would like to make a parity test procedure, but I would like to make it in assembler coz it's faster. If this is not possible with Hitech C compiler, could you please send me an efficient procedure written in C ? Thank you !
