Delete "List Check" and "Range Check" properties from entire data table

[#1]

Hello,

I need to loop through all the columns in xml import data tables and remove the "List Check" and "Range Check" properties throughout. I've tried several different iteration of doing this and nothing is working for me. Here is an example of non-working code:

dt = current data table();

//********************\\
colNames = dt << get column names( string, character );

For( i = 1, i <= N Items( colNames ), i++,
	Column(dt, i) << Delete Property("Range Check");
	Column(dt, i) << Delete Property("List Check");
	);

This produces the following error message. Any help resolving this would be appreciated. Sample data provided. Thanks!

Try this

Names Default To Here( 1 );
dt = current data table();
// Open Data Table: big class.jmp
// → Data Table( "big class" )
//Open( "/C:/Program Files/SAS/JMPPRO/16/Samples/Data/big class.jmp" );
colNames = dt << get column names( string );
For Each( {col, index}, colNames,
	Show( col );
	Try(
		As Column( col ) << delete property( "List Check" ) <<
		delete property( "Range Check" )
	);
);
