Read and Write .dat files

[hederson2801]

Hello guys, I need to read and write information in the .dat file. This file has a programming in C language. In it I have variables and logic. I would like to know if there is a way to read this file from a location on my computer, and change the values ​​of a variable. For example.

read

bool position = true

write

bool position = false.

There is a node for this?

Assuming the file is on the machine running node red (which may not be the one the browser is running in) then you can use a File In node to read the file, then make whatever changes you want and write it again using a File Out node.

The fact that you have to ask this makes me think you must be a beginner with node-red. If so then I recommend watching this playlist: Node-RED Essentials. The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.
