I want add this action to script jsl, but no concat's script description at source edit.

How should I use the Script for adding New Columns sequence?

dt = current data table();
dt << new column("new column name", character,
formula( char( :step_name || :param_name)
)
);

I suggest you take the time to read the Scripting Guide from the JMP Documentation Library
