Is there no way to create a self-extracting installer through the FB 7-zip functions? It should be simple, but it looks like I'm going to have to resort to using a DOS command to do it.

I should clarify - by “self-extracting installer” I mean not just a self-extracting ZIP file, but the installer you can create by including a config file. This is how the Firefox installer is created.

No we don’t have built in support for this, however it’s quite simple to do and the 7 zip help file has good information on how to do this. You will also need to download the 7x\_extra package from their website.
In FB, the Run Dos command will be what you need, as it relies on the dos copy command to concatenate files.
