The EXTENDED client error codes feature is enabled by specifying CLIENTERRCODES EXTENDED in the FTP.DATA data set used by the client. EXTENDED implies TRUE, meaning that client error codes are used for return code generation, and it supplements the information returned. See the following format of the return code:

ecyy

The return code returned to the user or batch job is the 4-digit ecyy value. This value can also be derived from the contents of message EZA1735I, which displays the standard return code and client error code.
