How to FTP a variable length file from linux to mainframe z/OS

问题

I could not FTP a variable length file to mainframe; the operation was success, but the dataset generated on mainframe is not correct; can anyone help me.

procedures.

1. I have created a variable length dataset on mainframe.

   DSN=.TEST.DATA1
   LRECL=16
   

   Its content have 5 records, each has 12 characters: 000001 11AAAA000001 000002 11AAAA000002 000003 11AAAA000003 000004 11AAAA000004 000005 11AAAA000005

2. download the dataset to linux using FTP client on a linux platform ftp -v -n< user prompt binary quote site rdw get TEST.DATA1 close bye EOF

3. the file was downloaded successfully.
4. upload the file back to mainframe ftp -v -n< user prompt binary quote site rdw recfm=v lrecl=16 put TEST.DATA1 TEST.DATA2 close bye EOF

5. the new generated dataset TEST.DATA2 on mainframe is not correct.

    000001     11AAAA00
    000002 0001    11AA
    000003 AA000002
   
    000004 11AAAA000003
    000005     11AAAA00
    000006 0004    11AA
    000007 AA000005
   

   It seems the RDW field was treated as data field, this is not I expected; I wish the TEST.DATA2 has same as TEST.DATA1.

Thanks.
