Explanation

IKJEFT01 (misspelled as IEKJEFT01 in the question) is the z/OS Terminal Monitor Program (TMP). It executes TSO commands, CLISTs, and REXX execs in a batch environment. This allows users to run commands such as OCOPY, OGET, and OPUT to copy files between MVS and other environments (like UNIX System Services).
