Thanks, and yep, the postfix notation allows for chaining commands together without parentheses. For example: 1 2 +; 3 * (The semicolon is used to indicate that the previous string (token) is a function and should be executed. In some instances this is implicit, like when the last string (token) in a larger command (like the one above) maps to a function name, in which case it will be treated as a function call even when no semicolon appears after it.)
