This procedure when run displays a random Magic 8-Ball phrase (the list was shortened to 16 different phrases to simplify the random number generation) and outputs it to the console, then exits back to MS-DOS. A 32 bit Xorshift routine was used to create the random numbers, and it was seeded using the computer's current time. <lang asm> .model small .stack 1024

Forth
ANS/ISO FORTH, GNU FORTH
This example defines CASE: ;CASE that create a vector table.
VECTORS compiles a specific number of execution vectors into memory from the data stack.
Responses are created as executable routines that return their Execution token to the Forth Data Stack.
The responses are retrieved from the data stack and compiled into a vector table, after which it is trivial for RANDOM to select any response.

This REXX version is modeled after the Ring entry.
The method used is to translate all blanks to pseudo-blanks, then extract and show a random phrase (after translating the pseudo-blanks back to blanks).
Also, this REXX version appends a period to the phrase as per the (linked) documentation. <lang rexx>/*REXX program simulates the "shaking" of a "Magic 8-ball" and displaying an answer.*/ $="It is certain ÷It is decidedly so ÷Without a doubt÷Yes, definitely÷Signs point to yes",

say space(translate(word(translate(translate($, '┼', " "), , '÷'), random(1, 20)), ,"┼")).</lang>
