Can someone tell me about undocumented sections in VBP files?

These are sections (and lines within those sections) in VBP files that VB6 will act upon when loading a VBP file, but that VB6 will never actually generate from any possible conditions in the VB6 IDE itself at the time of saving a VBP file. Fortunately though, VB6 won't overwrite them when re-saving a VBP file.

I know one of them actually tells the VB6 IDE to treat a given project as a console project! This isn't officially supported and isn't documented anywhere on the MS website. I remember reading it in an article YEARS ago when searching for how to make a console project. But now I can't find that same article, no matter what search terms I use in Google to specifically search for that article. I have typed in very specific things that should help Google narrow down what I'm looking for, search strings like "Make VB6 compile console project with undocumented lines in the VBP file", but Google isn't finding the article for me.

I don't think this is widely known knowledge either, as in my entire life I've only seen ONE ARTICLE ever mentioned this trick. I don't even know how it was originally discovered. Maybe some hacker decompiled vb6.exe?

Whatever the case, I've since forgotten myself what the name of this special line in the VBP file is to turn it into a console project, and so I'm hoping someone here can tell me. Furthermore, if you are aware of any other undocumented VBP lines like this, that perform various other unsupported tricks in VB6, please let me know.

Thanks in advance.
