How to include script using relative path?

[#1]

I have two scripts, main.jsl and dosomething.jsl that are next to each other in the same folder.

Main script has this in it:

relativePath = "./";
absolutePath = "c:\Users\myUser\Scripts\";
dosomething = Expr(
Include( relativePath || "dosomething.jsl" )
);

This dosomething does something all over the script, it's very handy to edit dosomething.jsl WHILE still running the main script.

So, when I do that using relativePath as written above - JMP crushes. But works fine when using absolutePath.

Now, I don't want to use absolute path. How can I use relative path in Include statement?

For instance, this works fine for Logo.png that lies next to these two scripts:

Picture Box( Open( "./Logo.png", png ) )

If relative paths not working with Include, is there any way to access the absolute path for the currently running script?

And again, formulating and writing down the question gave me an idea where to look for the answer.

So this works:

relativePath = Get Default Directory();
absolutePath = "c:\Users\myUser\Scripts\";

dosomething = Expr(
Include( relativePath || "dosomething.jsl" )
);
