Getting Started

Hello World

output "Hello, World!"

Variables

Variables are containers for storing data.

Creating Variables

Swas has no command for declaring a variable.

A variable is created the moment you first assign a value to it.

x = 5
y = "Mark"

Using Variables

To use the variables, simply reference them

output x
output y

Case Sensitive

Note: Variables names are case sensitive i.e. a = 5 is not the same as A = 5

Comments

A Comment starts with a //, and anything after them will be ignored:

//This is a comment
output "Hello, World!"

Operators

Operators are used to perform operations on variables and values.

Arithmetic Operators

Operator	Name	Example
+	Addition	x + y
-	Subtraction	x - y
*	Multiplication	x * y
/	Division	x / y
%	Modulus	x % y
inc	Increment	inc x
dec	Decrement	dec x

Logical Operators

Operator	Name	Example
==	Equals	x == y
!=	Not Equals	x != y
>	Greater than	x > y
>=	Greater than or equal to	x >= y
<	Lesser than	x < y
<=	Lesser than or equal to	x <= y

The Assignment Operator ( = )

The Assignment Operator ( = ) is used to assign a variable to a value.

If Else

An "if else statement" is written by using the if and else keywords.

Syntax

if condition {
  statement 
}
else {
  statement 
}

Note: The indentation isn't needed, it has been used here for readability

Example

name = input "Enter your name: "
if name == "John" {
  output "hi," + name 
}
else {
  output "bye," + name 
}

While Do

With the while loop you can execute a set of statements as long as a condition is true.

Syntax

while condition 
do {
  statement
}

Note: The indentation isn't needed, it has been used here for readability

Example

start = 1 
end = 10 

while start != end
do {
  output start
  inc start 
}
