−
The address list is the place where all the addresses will go that you think are usable.
+
'''function''' readBytes(''Address'', ''Bytecount'', ''ReturnAsTable'' )
  
−
The list can be navigated by using the keyboard and mouse. There are 2 ways to change a value in the list, by either double-clicking the value, or by selecting it and pressing enter. For all the other items in the list just double click on it and it will open up a new window allowing you to change it.
+
Returns the bytes at the given address
  
−
The check boxes allow you to freeze and unfreeze the address. If you freeze a address the address will not change until you unfreeze it. The value does change but Cheat Engine will restore the value to it's frozen state every few milliseconds (The number of milliseconds can be changed in the settings window).
+
===Function Parameters===
−
 
+
{|width="85%" cellpadding="10%" cellpadding="5%" cellspacing="0" border="0"
−
There are 3 types of freezing: Normal ('''='''), Allow Increase Only ('''+'''), and Allow Decrease Only ('''-'''). You can change the type of freezing by clicking on the symbol right of the check box. The allow positive and negative can be set also by keyboard's numeric '''+''' and '''-''' keys.
