How to check ping on Oldschool worlds:
1) Open up a completely fresh notepad.

2) Copy and paste the following lines of text in to the notepad document

ECHO off

SET worlds=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,65,66,67,68,69,70,73,74,75,76,77,78,81,82,83,84,85,86,93,94,87,88,89,90,91,92

FOR %%i IN (%worlds%) DO (
Echo | SET /p=World %%i
FOR /F "tokens=5" %%a IN ('Ping oldschool%%i.runescape.com -n 1 ^| FIND "time="') DO Echo %%a
)
PAUSE

4) Open the .bat file
