Dear Ashis,
You're right, there is a bug in my code. But you can rewrite the part that
selects the last 4 characters in a more robust way, like
%% return the last N elements of list L
fun {LastN L N}
{List.drop L {Max 0 {Length L}-N}}
end
The call to Max ensures that you don't drop anything from the list if its
length is less than or equal to N. Then the filtering may be fixed:
OzfFiles = {Filter Files fun {$ F} {LastN F 4}==".ozf" end}
Cheers,
raph
