Just to be clear there has never been a time when it was OK to modify the acad<release>.lsp file. Acad.lsp, acaddoc.lsp, and acad.rx have been the user created files set up for this purpose by AutoCAD you should have been using in 2000 as well. Now that AutoCAD and most organizations IT policies have blocked you completely it's time to do this the way you should have been doing it all these years. Ifreturns nil create one in theCode:(findfile "acaddoc.lsp")folder where permissions shouldn't be a problem. Appending your code after the last line will display whatever your code sends last as well as any errors it may generate.Code:(getenv "userprofile")
