Hello, I am writing a small single player MUD like hack'n'slash game. (Yes, I had a question with this before :)

The enemies and other NPC (non-player characters) of course have to walk around. Before now, everyone was allowed to take one step after the player had done something. Now I want to make it less "frozen".

So I first had a look at thread but my system (Windows 98 SE, ActivePerl 5.6.1) does not support that. So I had a look at fork. Well, that works fine, except for one thing: inside the fork, the data (such as player locations, NPC locations, all those stuff) are not correct.

So I grabbed the fork documentation and I found out that variables and such are copied. How can I, from within the fork, access the data of the main process?
