1: Introduction to PRSE syntax

PRSE is a C-like language. If you have experience with C or C++, you shouldn't have many problems writing a program with PRSE.

Primitives

There are 5 primitive types:

• bool
• int
• double
• char
• string

Arrays

Arrays in PRSE can be created for any primitive type, by adding '[]' after the type specifier.

Variables

Use this syntax to create a variable:

let a: int = 20;

Note that PRSE uses Resource Acquisition Is Initialization (RAII) principles for variable declaration. If you need to create a variable for later use, you still need to assign it some non-null value.

Functions

Syntax:

function Name (param_1: type): return_type {
    // Function body
}

param_1 can be any primitive type. You may define as many parameters as you need in the function, or you can omit parameters altogether. A function's return type can be any primitive type. You may alternatively use the keyword func in place of function.

Each parameter defined in a function must have a type attached to it. For instance:

function foo (bar: int, baz: double): string {
    // ...
}

is valid syntax, whereas:

function bit (bark, batch): string {
    // ...
}

is not valid syntax.
