Nasser, Sorry, can't add more here. I myself learned about these functions very recently from this post by Oleksandr Rasputinov: http://mathematica.stackexchange.com/questions/990/struct-equivalent-in-mathematica/1029#1029 And that's pretty much all publicly available information on this, I believe. These functions probably serve internal purposes, and so are undocumented. This is a normal practice, anyone who is willing to dig out and use undocumented functionality should accept that it is, well, undocumented. Cheers, Leonid On Thu, Feb 23, 2012 at 1:49 PM, Nasser M.
