Line 31: One or more large arrays are sometimes used to emulate in-program [[dynamic memory allocation]], particularly [[memory pool]] allocation. Historically, this has sometimes been the only way to allocate "dynamic memory" portably. Arrays can be used to determine partial or complete [[control flow]] in programs, as a compact alternative to (otherwise repetitive) multiple <code>IF</code> statements. ~~They~~In ~~are~~this ~~known~~context, inthey ~~this~~are ~~context~~known as [[control table]]s and are used in conjunction with a purpose-built interpreter whose [[control flow]] is altered according to values contained in the array. The array may contain [[subroutine]] [[Pointer (computer programming)\|pointers]] (or relative subroutine numbers that can be acted upon by [[Switch statement\|SWITCH]] statements) that direct the path of the execution of the program. ==Element identifier and addressing formulas==
