Techniques for making quick multiway decisions by subscripting have been called “table look-at” as opposed to “table look-up” [see P. M. Sherman, CACM 4 (1961), 172–173, 175].

Instead of basing a search method on comparisons between keys, we can make use of their representation as a Sequence of digits or alphabetic characters.
[…] a Node can perform a simple table lookup operation augmented with extrapolation or interpolation techniques to determine and apply the best 𝛼 and 𝛽 settings in response to dynamically changing conditions. The lookup time is O(1) and can be efficiently applied at runtime.
The following code implements a Table Lookup and dispatch function using JavaScript. The purpose of this function is to handle interrupts, that is, signals indicating the occurrence of an Event.
I (Ward Cunningham) helped electrical engineer Jeff Bradford complete a vector generator for the Projection Kanji Keyboard. Jeff simplified the ECL design by moving considerable logic into static ram lookup tables. I used APL's array manipulation to formulate and check the bit patterns that would fill these tables.
