Maybe you can try ConyEdit. It is a cross-editor plugin for the text editors, including Notepad++.
Follow the steps below:
1, keep ConyEdit running.
2, use the cc.gl a
command line to push data to array a.
3, use the cc.gl b
command line to push data to array b.
4, use the cc.p
command line to print the contents of the array a and array b.
