Hi Juha,
I believe Lazarus lacks a comprehensive programming guide to use it effectively.? Would be great if somebody can create a PDF guide running into hundreds of pages, covering everything from console, to full scale GUI applications coding. With thanks and regards,
Andrew

Ok. I will have a look.
I am no expert at all, so need to learn and dive deep. Will take some time.

It is perfectly possible. Try this:
In the Lazarus default application design-window,
- drop an Edit there
- drop a Label there
- drop a Button there
- double-click the Button. Write "Label1.Caption := 'Hello ' + Edit1.Text;"
- click the Run (F9). The application is compiled and runs.
- save your new project if you want to continue it later.
You have now created a standalone executable which can be copied and runs in any similar platform (OS).
What more, the same source code can be compiled in other supported platforms and it runs using the system's native GUI controls. No IFDEFs. Amazing!
This Hello app does not use threads. You can delete those automatically added IFDEFs from the .lpr file if you want, as Martin mentioned.
Juha
