/* Graphics Not Rendered in HTML */ There is a symbol (hash) table for each task. When a sym is not found, the parent task's sym table is checked. All tasks chain back to the System task. ZealOS sym tables are implemented with an array of linked-lists. A num is generated from a string by HashStr() to index into the array of linked-lists. Multiple strings can generate the same num, so linked-lists are built. Newer entries overshadow older ones. There are various types of entries. See Hash Entry Types. Symbol Look-up (Used many places including the JIT Compiler and Loader.) 1) Symbol name is hashed by adding and shifting the ASCII of all chars. 2) hash table->body[] array is indexed. 3) Linked-list is traversed until match of text and type of entry. 4) If not found, hash table->next table is searched. Duplicate entries are allowed -- they overshadow old entries. Address-to-Symbol Look-up (Slow because not important. We could use trees.) 1) FunSeg Cache is scanned. 2) Hash Tables are scanned.
