在脚本中如何用列号来代替列名称？

[#1]

 例如: 以下脚本是选取年龄是13岁的姓名、身高、体重列数据

在脚本中如何表示 用第4列、第5列来分别代替"身高"、"体重"列？

感谢帮助!

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
dt << Select Where( age == 13 );
dt << Select Columns( "name", "height", "weight" );
d3 = dt << Subset( Output Table( "A" ), Selected Rows( 1 ), columns( name, height, weight ) );

You can use the Column() function

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
dt << Select Where( age == 13 );
dt << Select Columns( "name", "height", "weight" );
d3 = dt << Subset( Output Table( "A" ), Selected Rows( 1 ), columns( column(4), column(5) ));

[#4]

dt << Select Columns( "name", "height", "weight" );

Could the  "height and weight" in this line of code also be replaced with column numbers?

Thanks Experts!

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
dt << Select Where( age == 13 );
c1 = Column( 1 ) << Get Name;
c2 = Column( 4 ) << Get Name;
c3 = Column( 5 ) << Get Name;
dt << Select Columns( c1, c2, c3 );
d3 = dt << Subset( Output Table( "A" ), Selected Rows( 1 ), columns( Column( 1 ), Column( 4 ), Column( 5 ) ) );
