Hi Ian,
you can use diary
https://octave.org/doc/v5.2.0/Diary-and-Echo-Commands.html#Diary-and-Echo-Commands
I didn't make it clear, but I want to be able to recall the commands using up and down arrow so diary does not do it for me.
In truth I can't see any reason why command history and open file are not kept up-to-date at the end of every command.
Cheers... Ian
