Warning while using inline assembly

I am using inline assembly in C but i am getting a warning as "UNRESOLVED EXTERNAL SYMBOL".The code is executing but i am getting only the warning. I set all these options:
Generate assembler SRC file
Assemble SRC file
Include in Target Build
I have attached my code below main()
{ #pragma asm mov a,#24 mov r1,#23 add a,r1 here: ajmp here
#pragma endasm
}
