DISPLAY NOTITLE TRN(IS=ON) MESSAGE-TYPE(IS=ON) ENTITY(IS=ON)

Can anyone tell me what does (IS=ON) represent in above display statement ?

This is documented in the Parameter Reference manual.

With this session parameter, you can suppress the printing of identical information in successive lines created by a WRITE or DISPLAY statement.

So, in a columnar report, you can eliminate repeated values.

A simple program will demonstrate what it does.

Without IS (defaults to OFF/False), note that "ADKINSON" is repeated.:
