OK, thanks! But I have another observation.  In the function:

void send_b(PGM_P src, char *dest)
    {
        char data;        
        while(data= pgm_read_byte(src++));
            {
                *dest= data; 
                dest++;
            }
            
    }
//======================

No code is generated for "dest++" . Why is this?

Thanks!
