Words within expressions and statements are separated by spaces. Lingo ignores extra spaces. In strings of characters surrounded by quotation marks, spaces are treated as characters.
If you want spaces in a string, you must insert them explicitly.
Uppercase and lowercase letters Lingo is not case sensitive-you can use uppercase and lowercase letters however you want. For example, the following statements are equivalent:
member ("Cat").hilite = TRUE
Set the hiLite of member "cat" to True
set the hilite of member "Cat" to True
SET THE HILITE OF MEMBER "CAT" TO TRUE
Set The Hilite Of Member "Cat" To True
However, it's a good habit to follow script writing conventions, such as the ones that are used in this book, to make it is easier to identify names of handlers, variables, and cast members when reading Lingo code.
