Message statement is not working?

I would like to place a message in the following method:

It's defined like this:

Position & cannot be delimited because the position is occupied until &

This is in the program:

MESSAGE: s029(zpom_001) WITH st_hrp1001-objid(8) st_hrp1001-endda(8), display like 'E'.

I inserted the (display like 'E' ) in so I can get the RED 'X' error message. If I take out the display like 'E', it works.

I get the following error:

Three-digit error number XXX required in the "MESSAGE EXXX..." statement.

Thanks for any help you can give?
