filespec[,...]

    Specifies one or more files to be purged. If you specify more
    than one file, separate the file specifications with either
    commas (,)  or plus signs (+). The asterisk (*)  and the percent
    sign (%)  wildcard characters are allowed in the directory, file
    name, and file type fields; however, no version number can be
    specified. As a default, the PURGE command purges all files
    in the current directory. There are no file name or file type
    defaults with the PURGE command. If an input file specification
    is a symbolic link, the symbolic link itself is purged. Because
    only one version of a symbolic link can exist, this command has
    no effect on that file.
