Where can I write an application on a laptop?

I just want to update my application, but I only have the 'WORDPAD' program on my laptop. The problem is that this program does not support all features for the format, so not everything on my application is as it should be. Some content is missing.

Is there a FREE program?

Try Open Office. You can use it to do almost anything that works with Word. Open and edit files including Word.

this is also a useful alternative to Microsoft for Excel and PowerPoint

I don't know anything free of charge but I would recommend you to write applications in Word.

Yes, e.g.

https://de.libreoffice.org/...ffice.org/

or

https://www.openoffice.org/de/

Openoffice and Libreoffice are free and can generate files in Word format.

What did you use to write the original application? You should only use the software for your private documents that you own yourself… 😉

Is there a FREE program?

Yes, OpenOffice. This is also available for Windows.

Download "LIBRE OFFICE" or "OPEN OFFICE" and install it - can do everything you need for a reasonably sophisticated layout and is FREE!

I didn't know, but it sounds good.

And also "read" such…

Wordpad can also read almost anything, but it does not generate Office documents, but RTF or XML.
