Long integer, multi-select list box
Ordinary long integers are stored as displayed in windows.
Multi-select list box values are stored as a series of 32 Ts or Fs, indicating which items are selected (indicated by a T) and which aren't (indicated by an F).
Special procedures need to be followed when importing data into a multiselect list field. Source data must be formatted as a series of 32 Ts or Fs representing the position of each item in the list, and whether the item is selected (indicated by a T) or not selected (indicated by an F). If a list contains fewer than 32 items, the unoccupied positions must be set to F. If you enter a constant for a long integer field that uses a multi-select list box control type, you must also use this format.
