IEBCOPY has been entered from TSO as a command processor. This message is issued because IEBCOPY was not written to be a TSO command processor but may function when so invoked while not providing all the services of a command processor (for example, prompting for missing/incorrect parameters, providing HELP information).
The severity is 0.
Processing continues.
Use the TSO CALL command to invoke IEBCOPY. Do not enter IEBCOPY as a TSO command or CLIST statement.
