How to write parameter infinity under MS windows xp command prompt?

Question

There is a binary exe that executes under windows xp command prompt. One parameter required is infinity (∞）. My system is win xp 5.1.26 (in command prompt window). How to write that? Thank you.

Answer 1

One way would be to copy the infinity symbol to your clipboard, right-click into the command prompt window and select "Paste". If that doesn't work, check the settings.

Alternatively, alt codes !
