# Dec

The opposite of **Inc**, the function **Dec** decrements an integer value by 1, and provides faster and cleaner processing than using a statement like **Eyes := Eyes - 1**.

Unless of course you were wanting to decrease the variable **Eyes** by a greater number such as 10, when you would use **Eyes := Eyes - 10**.

**Declaration**: Procedure Dec(var X: Integer); overload

Examples as below.

```pascal
procedure OnMapEvent(var Value:Variant);
var
  Eyes : integer;
begin // loop while Eyes > 10
   Eyes := 20;
 while Eyes > 10 do
 begin
      LogInfo('Eyes is equal to '+IntToStr(Eyes));
      Dec(Eyes);
 end;
end;
```

This example writes a decreasing sequence of entries to the log, starting with **Eyes is equal to 20**, and ending with **Eyes is equal to 11**.
