Local variable declaration

In Rell, local variables play a important role in storing and managing data within a specific scope. They provide a way to temporarily hold values that can be manipulated, utilized, or referenced within a limited context.

Constants in Rell

Constants are values that can't be changed after initiation. They may exist outside the scope of a function. They are declared using the val keyword, followed by an identifier and an assigned value. Here are some examples:

val x = 123;
val y: text = 'Hello';

Variables in Rell

Variables are declared using the var keyword. However, unlike constants, variables allow for value modification within their scope. They can't exist outside the scope of a function. Here are some examples:

var x: integer;
var y = 123;
var z: text = 'Hello';
