Parameter

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.
