I'm having a some trouble getting this to work and would appreciate some help.
I know that you can set a variable and unset it after N seconds, like this:
set -u10 %variable message
But what I want to do is to unset the variable depending on a value from an INI file. I figured I could type it like this, but it didn't work:
set -u$readini(filename.ini,section,item) %variable message
