You can find
here a very cool plugin for Eclipse, called Wordfile Editor. It is an easy to use Eclipse editor for all text based programming languages e.g. like VBScript, JavaScript etc. It is based on UltraEdits concept of wordfiles for syntax highlighting. The editor supports additional features, such as code folding and content assistants.
With this plugin and the possibilities of the External Tools menu in Eclipse you can configure your development environment very flexible.
I describe
here a way of integration via Shell and Batch view plugin. This is another way to reach an equivalent result.
Flexibility is very good, ABAP in Eclipse offers this.
