I work that way a lot too, and never remember to turn on journal. So
I wrote a routine
called grab_commands.pro that I can call at any point to grab all the
commands I've
used and put them in a file, like turning journal on and getting all
the previous
commands. It grabs commands from the recall buffer, which by default
only keeps a few
commands. In my IDL startup file I set !EDIT_INPUT=1000 which should
cover most cases.
It's been awhile since I've updated my public IDL library, but for now
I've put this
routine at http://fermi.jhuapl.edu/temp/grab_commands.pro
It should work for any version that has the IDL recall_commands
routine (not sure when that
came in, maybe IDL 5?). Once you get it just do grab_commands,/help
for all the deatils.
