Get a random sentence from a selection each time in Batch

Question

Is there a way of making it so instead of saying the same echo that you set every time, you can give a list of echos and it chooses a random one to say each time it reaches that

Answer 1

Yep. Here's a proof of concept.

@echo off
setlocal enabledelayedexpansion

set string[0]=This is the first random line.
set string[1]=This is the second random line.
set string[2]=This is the third random line.

set /a idx=%random% * 3 / 32768

echo !string[%idx%]!
