The current version, fully functional, holds in only 399 lines (af= ter going through J-P. Rosen's Normalize tool). It can be interesting for t= hose who are curious about how the "MA" part of that compression algorithm = is working. The code can be browsed here: http://unzip-ada.sf.net/za_html/lzma-encoding__adb.htm I've put a few notes about range encoding used in LZMA, here: http://gautiersblog.blogspot.ch/2016/08/lzma-compression.html Have fun Gautier
