 *
 * Permissions for variables.
 * PUBLIC means the variable can be read or written anywhere.
 * RESTRICTED means it can be read anywhere, but written only in the record.
 * PRIVATE means it can only be accessed in the record.
 *
 * The modifiers static declares that variable to be allocated, are allocated in
 * the parent's frame, and code is translated into the parent's frame.
