[#1]

How can I add unit in column property based on contain of file name. In this case if it has _Voltgae at the end I want V as unit. and if _Current at the end add A as unit.

Here is a simple example:

Names Default To Here( 1 );
dt = 
// Open Data Table: Big Class.jmp
// → Data Table( "Big Class" )
Open( "$SAMPLE_DATA/Big Class.jmp" );

colNames = dt << get column names( continuous, string );

For Each( {col}, colNames,
	If(
		Contains( col, "hei" ),
			Column( col ) << set property( units, "inches" ),
		Contains( col, "wei" ),
			Column( col ) << set property( units, "lbs" )
	)
)
;
