Programming in Symbian OS

This page is a tutorial about how one can use the Symbian OS API to write software

Overview

Hello World

Description

When started, this software will display a 'My Pascal Hello' message on the screen and then quit. The message will remain for about 5 seconds.

Notes

• User_InfoPrint will return a integer with a error message, but we just ignore it on this hello world
• We are using the procedural bindings, througth the symbian.pas unit, and not the object-oriented bindings

Code

QPasHello.ini

[Main]
EXENAME=QPasHello.exe
TARGETTYPE=EXE
UID2=0x100039CE
UID3=0xE1000002

[Files]
source0=QPasHello.pas

QPasHello.pas

program qpashello;

{$mode objfpc}{$H+}

uses symbian;

var
  aMsg: array[0..255] of Char;
begin
  aMsg := 'My Pascal Hello';
  User_InfoPrint(aMsg);
end.
