Pascal imposes quite strict program organization. Below you can find models for
writing legible and organized source files. For more information on file inclusion and
scope, refer to Units and Scope and Visibility.

Basically, the main source file has two sections: declaration and program body. Dec-
larations should be in their proper place in the code, organized in an orderly man-
ner. Otherwise, the compiler may not be able to comprehend the program correctly.

When writing code, follow the model presented below. The main unit should look like this:

program { program name }
uses { include other units }

//********************************************************
//* Declarations (globals):

//********************************************************

{ constants declarations }
const ...

{ types declarations }
type ...

{ variables declarations }
var

Name[, Name2...] : [^]type; [

0x123;] [

external;]

[

volatile;] [register;] [sfr;]

{ labels declarations }
label ...

{ procedures declarations }
procedure procedure_name(parameter_list);

{ local declarations }
begin

{ functions declarations }
function function_name(parameter_list) : return_type;

{ local declarations }
