Re: .Q.qp for splayed table

[sujoy]

If you refer here: https://code.kx.com/q/basics/syscmds/#l-load-file-or-directory

• serialized object, deserializes it into memory as variable name
• directory of a splayed table, maps the table to variable name, without loading any columns into memory

When you are running, l .t -> you are loading the object as t in root. Thus .Q.qp is showing t as 0

% ls -lrth t
total 16
