SFMC913I Recommended action: Specify ;!PARM SHAREAS and retry.
Explanation: Specifying ;!PARM NOSHAREAS has created a problem for the USS component of the FTP API because it is being forced to run in a separate address space from the VFTP client. The nature of the FTP command requires that it be allocated by the USS component of the FTP API. This will not be possible because a DD statement within the JCL has resulted in an MVS ENQ.
