Strings and interpolation
Put a value inside text with {…}, the way you would write it in a prompt:
name = "Ada"
say "Hello, {name}! You have {count of tasks} tasks."
Anything that works as an expression works inside the braces: "{price * 2}", "{upper name}". Write {{ or }} for a literal brace. Braces are only allowed inside text. Code structure stays brace-free (P013).
You can also join text with + or plus:
say "Hello, " + name
greeting = "Hi " plus name
In say and print, adjacent parts are joined in order:
set total to 14
say "Total: " total
See Lists, text, and numbers for upper, lower, trim, join, and split.
