demo1.1 Global Operators [Syntax Error]

[S1r_4zdr3w(OP)]

I tried to run the demo demo_1.1-basic_syntax_and_history.tau and got errors on global operators
I got the recent Tau version 0.7 (v0.7-alpha)
I'm running it on Windows with Virtual Machine Ubuntu OS.
The Tau demo run perfectly from the beginning but suddenly got error in this part.
