6. Typical structure in a basic program in Turbo Pascal 7

program ProgramName;

uses
// List of units (libraries) used

type
// Defining custom data types

const
// Definition of constants

var
// Declaration of global variables

{Declaration of subprograms (procedures and functions)}
procedure ProcedureName;
begin
// Procedure code
end;

function FunctionName: ReturnType;
begin
// Function code
end;

{ Main program }
begin
// Main program code
end.

1. program NombreDelPrograma;: It is the declaration of the name of the program.
2. uses: The units or libraries that will be used in the program are listed here, separated by commas.
3. type: This section defines custom data types such as records, enumerations, etc.
4. const: Here the constants that will be used in the program are defined.
5. var: Global variables that will be accessible from any part of the program are declared.
6. Subprogram Declaration: The procedures and functions that will be used in the program are declared. Each subprogram has its own code block delimited by begin y end.
7. Main Program: This is the block of code that is executed when the program starts. It is delimited by begin y end, and ends with a period (.).

7. The legacy of Turbo Pascal

7.1. Influence on other programming languages

7.2. Community of passionate programmers

7.3. Notable projects developed with Turbo Pascal

• Sidekick: A popular productivity app that combined a calendar, planner, calculator, and other tools into a single interface.
• Turbo Vision: A GUI component library for Turbo Pascal that facilitated the development of graphical user interface applications.
