The error message seems to tell, that the equal character "=" is not valid. How strange. Perhaps it is the space behind the =, which is a backspace charcter '\b' ?!
The code looks okay. How did you insert it to the command window? Simply try to type it again.
What is in the line above? Perhaps a continuation '...' and you've added the ">>" manually? I admit, this is wild guessing.
