+  The LOCATION statement (with its somewhat counter-
+  intuitive syntax) is used to obtain the address
+  of a variable.  A variable may be placed at a
+  particular memory address by declaring it as BASED and
+  then positioning it at run-time using the BASE..AT
+  statement. Most often this is done to access the values
+  stored in operating system variables and structures,
+  though it has other uses as well.
