That's what I thought too... But my testing in 701 seems to indicate
something else.
I have test.ijs on my Desktop with this on single line only:
scriptPath=.>_1{4!:3''
Now in clean Gtk Term window I type:
scriptPath
|value error: scriptPath
0!:0 <'C:/Users/greg/Desktop/test.ijs'
scriptPath
C:\Users\greg\Desktop\test.ijs
So it looks like =. works as local really only inside a function. Somewhere
some documentation is probably not update or something.
