XTREE offers a choice of two ways of providing the data for the list:

•   Array; this is recommended, as it provides the most flexibility and is required for some of the more advanced features

•   Sequential file; most convenient for simpler configurations. Both fixed width and CSV formats are supported.

XTREE supports three types of output:

•   A selected "item" (aka "row" or "record"). This is referred to as "single-selection mode."

•   An array of selected items ("multiple-selection mode").

•   An array of updated cell values (either checkbox values or text strings). This only applies when the data contains editable cells; see flags XTF_EDITABLE, and advanced coldef column formats E, u, U and T.

Not all features support all types of input or output, or there may be differences in the way the parameters are interpreted or mapped. So as you read the documentation, please be alert for qualifications which reference one or more input/output combinations, such as "single-selection array mode" or "multiple-select file mode."
