I want to do it with FTP - GET commad itself. Is it possible?
No, it is not possible. The GET command retrieves data -- nothing more, nothing less. You could use QUOTE LOCSITE to define the LRECL, BLKSIZE, and DCB characteristics of the file you want to create on the mainframe, but you cannot do so with the GET statement. You would use QUOTE LOCSITE as long as the FTP job is running on the mainframe -- a QUOTE SITE command would affect the server, not the mainframe. If the FTP is running on the remote server going to your mainframe, you would use QUOTE SITE.
