Programming 8051 in Multisim (Using C)

Question

Multisim 11
when i 'm getting start writing C for 8051 in multisim, an error occurs.
I used to use keil c compiler,so I don't know how to use hi-tech compiler.
even so, I wrote a simple LED blanking program, which has problemsin it.
the following is my code
===========================================================
#include    <htc.h>
#define LEDPin=P27;
void delay(unsigned int);
void main()
    while(1){
        LEDPin = 1;
        delay(10000);
        LEDPin = 0;
        delay(10000);
void delay(unsigned int x)
    unsigned int i;
    for(i=0;i<x;i++);
===========================================================
When I tried to build it, it kept saying that there's error in the line with red mark.(expression syntax)
Could anyone tell me where I did wrong?

Answer 1

Your define statement appears to be incorrect.
#define LEDPin=P27
should be......
#define LEDPin   P27
Also, I use PIC micros and the naming convention used is (for example) RA5 which means Port A, bit 5.  Check to make sure P27 actually maps to a pin.  Sometimes the assembly definitions are not the same as the C definitions.
