Check if variable with name s1 exists on the global heap (has been assigned). If so, 1 is pushed to the stack else 0. Global variables can be accessed by any script on the map.

# In one script:
42 ->*myGlobalVariable
# In any script on the same map after that point:
"myGlobalVariable" -?!* if
    "myGlobalVariable exists."
else
    "myGlobalVariable does not exist."
endif
trace
# Puts "myGlobalVariable exists." in the debug window.

	stack.Push(new Data(GameSpace.instance.globalHeap.ContainsKey(GetStringFromStack()) ? 1 : 0));
