[Jprogramming] J901

[Henry Rich]

math/calculus is described only in the header of calculus.ijs. It has 
replacements for d. D. D: .  It is missing some exotic derivatives but 
probably not anything you would need.

The 9.01 release is described at 
https://code.jsoftware.com/wiki/System/ReleaseNotes/J901 .

If you are going to let students loose on J in the classroom I recommend 
that you learn about the lint addon.  I wrote it to defend myself from 
having to debug everyone's missing ) and misspelled words.  I have some 
other classroom tools that we can talk about privately.
