you can load the lab from an ijs, using this boilerplate line.
1!:44 MYDIR =: getpath_j_ '\/' rplc~ > (4!:4<'thisfile'){(4!:3) thisfile=:''
sets working dir to the same as file that opened it.
so you can now just
load 'myfile.ijs'
(without the 1!:44 setter, still pretty easy)
load MYDIR ,'myfile.ijs'

Subject: Re: [Jprogramming] Gustafson's Unums Revisited
Is there a way for the unum lab to discover where it was started from, and
then set the working directory to that location, rather than having the
user have to set the directory?
