Version 2668 was committed by steve on Tue, 13 Aug 2013 PartFilter extract 1) from end, 2) initial and final ranges. Use negative numbers to take a part from the tail of the value list. Use the "<" or ">" operator (in addition to ":") in order to return a concatenation of all the parts before or after a certain part. The default behavior is not changed and this come at the expense of just 2 logical "IF" more when no operators are specified. Example, if the value is "Aa#Bb#Cc#Dd#Ee" part:#:1 returns Aa part:#:-1 returns Ee part:#:-2 returns Dd part:#>1 returns Bb#Cc#Dd#Ee# part:#<5 returns Aa#Bb#Cc#Dd# part:#<-1 returns Aa#Bb#Cc#Dd# - Enrico Liboni
