Modification to Get Column Names() function

Mark_Zwald

Many users often want to create a variable column list and use that to pass into another function.  For example something like this:

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Semiconductor Capability.jmp" );

cols = dt << Get Column Names( );
pnp_cols = {};

For (i = 1, i <= N Items(cols), i++,
	If ( Contains( cols[i], "PNP" ),
		Insert Into(pnp_cols, cols[i])
	);
); 

obj = dt << Process Screening(
       Process Variables( Eval(pnp_cols) ),
       Select All,
       Show Charts as Selected,
       Control Chart Builder
);

It would make logical sense for the Get Column Names () function to allow to specify a string matching criteria so as to not need to create the for loop.  The syntax might look something like this:

pnp_cols = dt << Get Column Names( Continuous, "PNP");

Agreed!
And more broadly, it would be great to easily apply a character function to a list of strings, the same way you can apply a numeric function to a list of numbers. The authors of the JSL companion suggested something similar, even wrote some utility functions to achieve this.
