Batch mode refers to emacs started with the -batch command line argument, which sets the `noninteractive' variable. There is no compiled mode. An Emacs Lisp function may be compiled (as may forms aka symbolic expressions in general), which is what happens when you byte- compile a .el file into a .elc file. A function whose definition contains an interactive spec is called a command, which can be invoked interactively via `M-x' (execute-extended-command) whether it has been compiled or not. Any form can be evaluated via `C-x e'. I just fooled around and find that `M-x' does return the result of the interactively executed command: (setq foo (execute-extended-command nil)) C-x e C-x C-f /tmp/foo RET ; returns: # Perhaps you mean that `M-x desktop-height-approx' doesn't report anything to the user. I think what you want is something like: (let ((deskheight ...)) (if (interactive-p) ; called via M-x (message "%d" deskheight) deskheight)) -- Kevin Rodgers
