EZA1720I

REPLACE option not allowed for UNIXFILETYPE=FIFO
Explanation
 You entered a get or mget subcommand,
specifying the REPLACE option and a z/OS®  UNIX local file when UNIXFILETYPE=
FIFO was configured.  The REPLACE option is not valid for z/OS UNIX files
when UNIXFILETYPE=FIFO is configured.  If the local file is a z/OS UNIX named
pipe, you cannot overwrite the contents of the named pipe.  Writing
into a named pipe always appends to the contents of  the named pipe. 

System action
 FTP stops processing the current subcommand and
prompts you to enter another  subcommand. 

Operator response
 Not applicable.

System programmer response
 None.

User response
 If the local file is a z/OS UNIX regular
file, issue the LOCSIte subcommand  with the UNIXFILETYPE=FILE parameter.
 Then issue the original subcommand again.     
 If the local
file is a z/OS UNIX named pipe, issue the subcommand without
the REPLACE parameter.   The incoming data will be appended to the
contents of the  named pipe. 

Problem determination
 To determine whether a z/OS UNIX file
is a regular file or a named pipe, use  the z/OS UNIX ls command.
See the information about the long output format in z/OS UNIX System Services Command Reference.
