Re: [Bug-apl] .apl.history file?

[David B. Lamkins]

Thanks, Jürgen.

I see what's happening now: The history file is not enabled when input is from 
a pipe, which is the case when I run akt|apl. The history file works as 
expected when input is from a terminal.

I guess I should finally get around to rewriting akt to use forkpty(). :)
