I have used UNDEFINE for a few commands in my acad.lsp file. However, I don't like the fact that the undefined commands get "advertised" (ie - written to the command prompt) during startup like so: UNDEFINE Enter command name: VBAMAN UNDEFINE Enter command name: VBAIDE UNDEFINE Enter command name: VBARUN UNDEFINE Enter command name: PLOT Is there any way to supress this behavior? I've tried putting a (princ) after the calls but to no avail. Any other ideas? TIA, Mark Sanchez
