activation record


er> (Or "data frame", "stack frame") A data structure containing the variables belonging to one particular ef="module.php?name=Lexikon&file=search&eid=1&query=scope">scope (e.g. a procedure body), as well as links to other activation records. Activation records are usually created (on the ef="module.php?name=Lexikon&file=search&eid=1&query=stack">stack) on entry to a block and destroyed on exit. If a procedure or function may be returned as a result, stored in a variable and used in an outer scope then its activation record must be stored in a ef="module.php?name=Lexikon&file=search&eid=1&query=heap">heap so that its variables still exist when it is used. Variables in the current ef="module.php?name=Lexikon&file=search&eid=1&query=scope">scope are accessed via the ef="module.php?name=Lexikon&file=search&eid=1&query=frame pointer">frame pointer which points to the current activation record. Variables in an outer scope are accessed by following chains of links between activation records. There are two kinds of link - the ef="module.php?name=Lexikon&file=search&eid=1&query=static link">static link and the ef="module.php?name=Lexikon&file=search&eid=1&query=dynamic link">dynamic link.
