Wolfram: Global Variable

By Xah Lee. Date: . Last updated: .
Set[x, y]

🔸 SHORT SYNTAX: x=y

make x to have value y

Effectively, this is how you create a global variable.

💡 TIP: builtin variable and function names start with an Uppercase letter. You should have your variable and function names starting in lower case.

(* global variable, of current session  *)
x = 2

💡 TIP: Technically, Set creates a syntax transformation rule. When the pattern on left-hand-side occur, replace it by right-hand-side.
