Subject: Re: [Jprogramming] Obtaining the file path of an ijs file
BINPATH_Z is similar to what I want (it's closer, since it's a noun rather
than a verb), but it only shows the file path of the main J bin folder. I'm
looking for something similar to Greg's code, but rather than outputting
where an object in particular is defined, I would just like to know where
the current ijs file is located. For example, if an ijs is on a folder named
"examples" on my desktop (on Windows 7), than I want a verb in my ijs that
can output "C:\Users\Neill\Desktop\examples". However, I want the verb (or
noun like BINPATH, if there exists one) to be flexible, finding a different
file path if the ijs is moved elsewhere. Thank you for the quick responses!
