The InsCol Command inserts a new column into the database. All columns to the right of the inserted column will have their column number increase by 1. The column is inserted at the position specified by its column number.
The Command name can be anything you like, it makes no difference when the sequence is run and is purely for organisation purposes.
The 'Command Type:' line reminds you of the Command Type as you might choose not to put it in the Command's name.
The remaining properties are specific to this Command Type.
Column Number - The column number to insert the new column at. It can be an interger or parsed from a variable value.
