Just entering _endp on its own in the command line is not a command, so no wonder you are confusing AutoCAD. Endpoint is used when the command is asking for a positional input from the user.
I didn't enter it but used the toolbar option Osnap which is under toolbars-Autocad-Object snap, the thing is when i try to use it by clicking on any of the tools on the bar it displays the message noted above in the command line!
Any help...
As eldon stated, you can't use these by themselves. You have to use them in combination with another command. Try this, type LINE at the command line and then hit Enter. Now click on "Endpoint" on your Osnap toolbar.
