>From 'info as': Local Symbol Names ------------------
Local symbols help compilers and programmers use names temporarily. There are ten local symbol names, which are re-used throughout the program. You may refer to them using the names `0' `1' ... `9'. To define a local symbol, write a label of the form `N:' (where N represents any digit). To refer to the most recent previous definition of that symbol write `Nb', using the same digit as when you defined the label. To refer to the next definition of a local label, write `Nf'--where N gives you a choice of 10 forward references. The `b' stands for "backwards" and the `f' stands for "forwards". -- Grant M.
