$WW,1$There are symbol(hash) tables maintained by each task.  When a symbol is not found, the parent task's symbol table is checked.  All process chain back to the $FG,2$Adam$FG$ task.

LoseThos symbol tables are implemented with an array of linked-lists.  A number is generated from a string to index into it.  Since multiple strings could generate the same number, a linked-list is built.  Newer entries overshadow older ones and entries are never removed.  There are various types of entries.  See $LK,"Hash Entry Types","MN:HTT_SYS_SYMBOL"$.
