Wow! You have a lot of problems with your code here.

First, you should NEVER put a semicolon at the end of an "if" statement, like this:

Code:

if(select=0);

Or your code won't work. Period.

Also, the statement "select-50" is just an expression. It does not change the value of "select". To subtract 50 from "select", you have to type:

Code:

select -= 50;

There should not be any declaration for "key_cuu" in your script; that is handled automatically when you include "acknex.h"

Here's something else I should mention:

Code:

if(select = 0)
{
  select = 0;
}

This is redundant. This means: if select is 0, make it 0. Why do we need to do that? "select" is already 0 in case the "if" statement is true.

One last thing; if "select" is a panel pointer, you can't shift it up by subtracting 50 from it. For that, you have to type:

Code:

select.pos_y -= 50;

Code:

// sample function
void sample_fn() {
	while(1) {		// loop for-never
		if (key_cuu) {
			beep;	// <- specific job (unspecified) = beep
		}
		wait(1);	// wait one frame
	}
}

void main() {
	sample_fn();	// call sample function
}

or just call the function when the key is pressed rather than making an event

Code:

void foo(){
   //do your do
   beep(); // beep once
   
   //or keep beeping
   while(key_cuu){
      beep();
      wait(1);
   }
}

void main(){
   on_cuu = foo();
}

Code:

if(select=0)

is not a comparison, but an assignment, and will always evaluate to false.
