Programming 8051 in Multisim (Using C)

[lslsls]

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?

Both od them are using assembly, but I'm using C.

what I don't understand is why a simple describe that set LEDPin to high or low got some problem in syntax.

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.
