My problem is with calling a custom command from the command line. The command is successfully called from a menu item contained in a partial CUI. The command, as shown below, is RELIMIT. Since the command is defined as RELIMIT in the Comand Name field I expected this would be the value submitted from the command line. Again, the operation works when selected from the menu in the partial CUI, but when entered from the command line I get the following message: Unknown command "RELIMIT". Is there somewhere else I need to define this command (acad2009.lsp, perhaps)?
