[Jprogramming] Name conflict in J system scripts - who cares ?

[Anssi Seppälä]

Thanks, just updated Package Manager but the problem is still there. However it is easy to fix by adding a erase line to jzplot - script. 

How it is informed when base library is rebuilt?

Sorry, it should be Henry who fixed it.

The reason appears to be in a name conflict in two different scripts that are added in same build: dll.ijs and jzplot.ijs. Both scripts declare name "endian": jzplot.ijs locally in class locale and dll.ijs globally in locale z and. The second assignment causes domain error while running the script.
