Greetings, This bit of code works in ACAD 2204 (setq loaded (menugroup "DSI_PID")) But not in R13. I want to load partial menus in R13 in ACAD.LSP since I have to use 13 at a customer site. I have no problem loading the partial menu in ACAD.LSP for 13 but once loaded I get errors when I open a new drawing since the partial menus are already loaded. I can't figure out the equivalent to: (setq loaded (menugroup "DSI_PID")) for R13. I posted a similar question in the ACAD 13 forum a while back but apparently there are only about 6 people in the world still using 13 and they all have questions and no answers. Thanks for any help, Doug Doug
