Hi Brian,
Nothing gets automatically re-computed -- which is good. If you want
to re-compute anything, you should make use of a function which needs
to be called each time you have new/ different input variables.
Perhaps it should be added that it is not necessary to write a formal
function. For example there's the command log that automatically records
everything (well, almost) you did in a gretl session. See Tools/Command
log. That is basically a script you could replay (or parts of it
probably) again to update the construction.
cheers
