Why level do not become '1'?
It shows me only LEVEL = 0
Code:

#include <18F2520.h>
#fuses NOWDT,NOMCLR,intrc
#use delay(internal=8M)
#use rs232(baud=9600, xmit=PIN_a1,rcv=PIN_a2)

void main()
{
while (true)
   {
   int level;
   output_high(pin_a0);
   delay_ms(500);
   level=input_state(pin_a0);
   printf("\fLEVEL = %d",level);
   }
}

Don't declare local variables (such as 'level') in the middle of code. Put
them at the start of the function.

I'm so sorry I lose your time. The mistake was all mine. My code is for 18f2520 and I had test it on 18f2431. I don't know how the **** display works properly Shocked and some other functions don't. So the problem was solved!
Thank you anyway!
