  1. Why we can create path to destination before we sign in to destination?
    or it just create command and at the end just execute step?

  2. If I would like to run this JCL by myself, I need to create the folder path in testing server ?

I run it myself but found error like this

IEF344I NATTOUT1 COPYOUT HFSOUT - ALLOCATION FAILED DUE TO DATA FACILITY SYSTEM ERROR
IGD17501I ATTEMPT TO OPEN A HFS FILE FAILED,                                   
RETURN CODE IS (00000081) REASON CODE IS (0594003D)                           
FILENAME IS (/BBBB/XYX/CXCXS)                                                 
IEF272I NATTOUT1 COPYOUT - STEP WAS NOT EXECUTED.

Thank you very much

  1. Set the home directory of the unix user to the destination directory.
  2. Not if the directory exists, and you have write permission.
put /BBBB/XYX/CXCXS VTESTX.TXT  
!rm CXCXS

This does not appear to be correct. Based on the put statement, the script is not running in the directory that contains the filef that you want to delete.
also i would not delete the source file until the transferred file has been processed.
