I use the session history (in bash) all the time.

I've taken to using a hack in DCL, saving and then reloading the recall 
buffer, too.  Makes for an easier mental restart, when getting back to 
work after logging out overnight, or after restarting coding after a 
reboot, etc.

When you can search for and recall commands, edit them if and as 
needed, and resubmit, the history becomes a command cache.
