Changes

Variables are declared with the by '''var''' keyword. Variable declarations must have Declarations require a type, or initializer, or both.

var myVariable1myVar1: intreal;

We use '''const''' and '''param''' can be used to declare runtime constants and compile-time constants respectively. A We can set a '''const''' must be initialized in place, but can have its variable's value generated at runtime. A But '''param''' must be known variable requires to set it at compile timebeginning.

const myConst: real = sqrt(myVariable2myVar2);

All three variable kinds We can be qualified by use the '''config''' keyword. This allows to override the initial value to be overridden on the command line.

config var myVariable2myVar2: bool = false; //./variable --myVariable=true
