Object The control whose choices are to be set. Default is the current control. The control should be a type that can take a list of choices (a list, radio button or table).
Variable The name of the variable containing the selections.
SubscriptType A single letter (default is I) identifying the contents of the subscripts in Variable, one of: A (application identifiers), I (internal identifiers), T (titles), R (rows), C (columns). Multiple letters indicate multiple subscripts. Rows and columns apply to table components only.
The macro %%SetSel causes the current selections in a control to be set from the list of already-set choices. It is primarily useful to set the default selections in a control.
Pre-existing selections are not first cleared; to do this use %%ResetSel.
Since the selections must be made from pre-existing choices, only a single subscript is supported. However, that subscript need not be an internal identifier.
Note that the definition of the control must permit the number of selections presented.
