   *   <dd>FTPClientObj.listFiles(parser,filename);
   * <LI>You'll get back the list as an array of FTPFiles like this
   *   <dd>FTPFile[] myNTFiles = FTPClientObj.listFiles(parser,filename);  (or)
   *    <dd>FTPFile[] myNTFiles = FTPClientObj.listFiles(parser);
   * <P>
   * That's all there is to it.
   * <P>
   * Each FTPFile object is populated just like any other FTPFile
   * object. The only thing not implemented at this time is the file
   * permissions, but I can do it if there is a real need for it.
   * <P>
   * !NOTE/WARNING!:Before you pass the parser to listFiles, make sure you are in 
   * the directory that you need to be. This parser will return the filtered
   * files from the directory it is in. This becomes crucial specialy if your
   * goal is to delete the output of the parser.

   * <P><B>USAGE:</B></P>
   * <LI>Create an instance of OS2FTPEntryParser</LI>

   * to look for </LI>
   *   <dd>FTPClientObj.listFiles(parser,filename);
   * <LI>You'll get back the list as an array of FTPFiles like this
   *   <dd>FTPFile[] myOS2Files = FTPClientObj.listFiles(parser,filename);  (or)
   *    <dd>FTPFile[] myOS2Files = FTPClientObj.listFiles(parser);
   * <P>
   * That's all there is to it.
   * <P>
   * Each FTPFile object is populated just like any other FTPFile
   * object. The only thing not implemented at this time is the file
   * permissions, but I can do it if there is a real need for it.
   * <P>
   * !NOTE/WARNING!:Before you pass the parser to listFiles, make sure you are 
   * in the directory that you need to be. This parser will return the filtered
   * files from the directory it is in. This becomes specially crucial if your
   * goal is to delete the output of the parser.

  /**
   * This Class uses the FTPEntryParser class to validate the input string.
   * It also requires the NetComponents library version 1.3.7 or later
   * and the OROMatcher library for the regualar expressions stuff.
   *
   *
   * <P><B>USAGE:</B></P>
   * <LI>Create an instance of VMSFTPEntryParser</LI>
   *   <dd>VMSFTPEntryParser parser = new VMSFTPEntryParser(boolean);
   *  <dd><code>True</code>  = returns all versions of a file with the respective

   * ;#
   *  <dd><code>False</code> = only the last version will return <B>(Default)</B>
   * <LI>Create an instance of FTPClient</LI>
   *   <dd>FTPClient FTPClientObj = new FTPClient();
   * <LI>Connect to the NODE </LI>
   *   <dd>FTPClientObj.connect();
   * <LI>Login to the NODE </LI>
   *   <dd>FTPClientObj.login(username,password);
   * <LI>Switch directories if you have to</LI>
   *   <dd>FTPClientObj.changeWorkingDirectory(thePath);
   * <LI>You might want to check if you are truly in a VMS System</LI>
   *   <dd>And how do I do that you ask? easy...  VMS is such a wonderful OS 
   * that when we do   <dd><B>String am_I_VMS =  FTPClientObj.getSystemName()</B>
   *   <dd>it returns NULL, while everyone else returns the FTP servername
   * <LI>Call listFiles passing the newly created parser and a filename or a mask
   *  to look for </LI> <dd>FTPClientObj.listFiles(parser,filename);
   * <LI>You'll get back the list as an array of FTPFile objects like this
   *   <dd>FTPFile[] myVMSFiles = FTPClientObj.listFiles(parser,filename);  (or)
   *    <dd>FTPFile[] myVMSFiles = FTPClientObj.listFiles(parser);
   *    <dd>If <code>filename</code> is a filename and versioning is OFF,
the 
   * version <dd>you requested will come back without the ;#
   * <P>
   * That's all there is to it.
   * <P>
   * Each FTPFile object is populated just like any other FTPFile
   * object. The only thing not implemented at this time is the file
   * permissions, but I can do it if there is a real need for it.
   * <P>
   * !NOTE/WARNING!:Before you pass the parser to listFiles, make sure you are
   * in the directory that you need to be. This parser will return the filtered
   * files from the directory it is in. This becomes crucial specialy if your
   * goal is to delete the output of the parser.
