version 2
This REXX version is modeled after the Ring entry.
The method used is to translate all blanks to psuedo-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.*/ $= "It is certain ÷It is decidedly so ÷Without a doubt ÷Yes, definitely",
"÷You may rely on it ÷As I see it, yes ÷Most likely ÷Outlook good ÷Signs point to yes", "÷Yes ÷Reply hazy, try again ÷Ask again later ÷Better not tell you now", "÷Cannot predict now ÷Concentrate and ask again ÷Don't bet on it ÷My reply is no", "÷My sources say no ÷Outlook not so good ÷Very doubtful"
@=translate(translate($, '┼', " "),, '÷') /*trans: blanks─►psuedos, seps─►blanks.*/ say space(translate(word(@,random(1,20)),,"┼")). /*stick a fork in it, we're all done. */</lang>
- output when invoking the REXX program:
Reply hazy, try again.
