JSL Identify Path of the Currently Running Script

[#1]

When running a script (either from the script window or by triggering it from the add-in) I would like to be able to either (1) get at the location of the directory that the script window is in or (2) get the id of the add-in that contains the script. JMP knows this because it had to open the script to start executing this. Is there a way to do this?

I know I can do this in an add-in context by using $ADDIN_HOME(id). The issue here is I have a common include that I am packaging in multiple add-ins, and I'd rather not have to change the file for each different add-in. I can see myself accidentally making a copy of the common include from add-in #1 to add-in #2 and forgetting to change the id in the include so that it uses the right path in add-in #2.

I like Jeff's solution. But there is a dedicated utility function, too, for this purpose. Here is an example:

Convert File Path( "$HOME", Windows );

It can do more than change the format from POSIX to Windows. See Help > Scripting Index > Functions > POSIX.
