How can I read/write .txt file on Simulink environment?

As you might know, there is no block for reading or writing data to .txt format in Simulink model library. (PLEASE DO NOT tell me use .mat format instead of it)

So I firstly used Interpreted MATLAB Function containing fopen, fprintf, and fscanf codes inside.

However, I found that it triggers saving 0 values at initialization stage.

This lead me to think of using the S-function block, which seems to can handle initialization stage separately so that I can neglect the saving procedure at initialization stage.

Is there any source file or even a link that I'm looking for?

There is no way available to write to a text file directly in Simulink. You can use the "To Workspace" block or "To File" (a .mat file) to store what data you want to.

Then with that data, you can use save() in Command Window to save the data to a text file as shown:

save File Data -ascii

You can also use MATLAB Function Block in Simulink to do saving
