Variables

Caliper Script does not require that you declare variables before you use them. The type of a variable is determined automatically by an assignment statement. For example:

x = 1 + 2 + 3	// x is an integer
y = 4.357	// y is a real
z = "Hello, World!"	// z is a string
pt = ClickCoord()	// pt is a coordinate
arr = {1, 2, 3, 4, 5}	// arr is a 5-element array

A subsequent assignment statement can change the type of a variable:

x = "Done!

// x is now a string

Variable names must begin with a letter, and can contain letters, numbers, and underscores. They can be of any length, and are case sensitive.
