bug in Resource Center "Internet chat" stack?

[Nicolas Cueto]

Hello,

While learning about sockets and global arrays, I found a problem with
the following line in Rev's "Internet chat" stack:

 delete lChatterArray[s]

This is wrong, right?

Cause it began to work only once I changed it to:

  delete global lChatterArray[s]

Posting in case other's too hit on this bug -- if indeed it is a bug.
