Is there anyway to close a drawing completely from the command line

I'm trying to use a script to print multiple drawings and can't close the drawing from the command line  with out having the Save Changes message box opening?  Other commands have the - minus sign in front of the command to redirect all commands to the command line just for the purpose of script files, but close does not have this option?  Also What is the difference between CLOSE and _CLOSE? IS there a dialog box disable command for the message box? Is this the same in other version?  Currently using V1R2
