setq

eval-expression (‘M-:’, ‘C-j’)

To execute such an expression, type ‘M-:’ (‘eval-expression’) and enter the expression in the minibuffer (*note Lisp Eval::). Alternatively, go to the ‘*scratch*’ buffer, type in the expression, and then type ‘C-j’

The only way to alter the variable in future sessions is to put something in your initialization file.
