Craig — I don't know, but here's an example of what can cause the "Can't re-enter AutoLISP" error (kids, don't try this at home): .. Command: (setq pt1 (getpoint "\nPoint: ")) Point: (getpoint) Can't re-enter AutoLISP Invalid point. Try again: .. After the first expression is entered, the GETPOINT function is active and waiting for input. If we try to respond to the GETPOINT function's prompt with another GETPOINT function, that's when we get the error. Does this help? I can think of any number of situations where it would be possible to attempt to do something like this, only to be doomed to failure (of course). One caveat about AutoLISP and menus. There is a DOS imposed limitation on the length of any line of text which, for some probably very good reason, effectively limits the length of any single AutoLISP expression contained in a menu macro to 255 characters…UNLESS explicit carriage returns are included in the menu item/AutoLISP expression before the 255th character! — Brad ..
