How I can change the data type from "continous" to "characters" from all the columns in current data table in one JSL sentence ?


For each column(
	col,
	dt,
	If( col << Get Modeling Type == "continous" & Contains( col << Get Name, "Layer Count" ),
		col << Set Data Type( Character )
	)
);

AI is quite bad with JSL, Scripting Index or using JMP to create example script is much better. 

Here is basic example

For Each({colname}, Current Data Table() << Get Column Names("Continuous", "String"),
	Column(Current Data Table(), colname) << Set Data Type("Character");
);

JMP created script

// Standardize column attributes
Local({old dt = Current Data Table()},
	Current Data Table(Data Table("Big Class"));
	For Each({col, index}, {:name, :age, :sex, :height, :weight},
		col << Set Data Type(Character(7)) << Set Modeling Type("Nominal") <<
		Compact()
	);
	Current Data Table(old dt);
);
