HCS08QE8 - SP manipulation - Code Warrior 6.1

Hi all,

I want to manipulate the stack pointer with an macro.

I tried this with the following code which doesn't work.

#define __SetSP( x ) __asm LDHX #x; __asm TXS;

error message (C18103: Factor exptected).

Have anyone an solution to do this?

Hello,

The following seems to give the intended result.

#pragma NO_STRING_CONSTR
#define __SetSP( x ) __asm LDHX #x; __asm TXS

Without the pragma, the presence of the '#' character within the inline assembler instruction confuses the C preprocessor when it expands the macro.

Regards,

Mac
