The 80-byte LRECL must be changed to match the zip file. This is one reason we never email zip files but use FTP to transfer them. You could change your first file from FB,80 to VB,84 and use a DCB block size override on the first DD name of the concatenation to indicate the block size of the zip file. Otherwise, you will have to ensure both files in the concatenation have the same DCB attributes.
