MakeValidTSlotRange

Declaration:

TMat4D.MakeValidTSlotRange (var LowTSlot, HighTSlot: integer): integer;

The method MakeValidTSlotRange ensures that the matrix time slot indexes LowTSlot and HighTSlot are within the valid index range of the matrix (i.e. they are greater or equal to 1 and less than or equal to NrOfTimeslots). If any of the two variable parameters falls outside the valid range, it is adjusted to the nearest limit. Passing a zero value to both parameters returns the minimum and maximum range values (i.e. 1 and NrOfTimeslots). The function returns the following codes:  0 ... both LowTSlot and HighTSlot are within the valid range, no adjustments made -1 ... LowTSlot and/or HighTSlot have been adjusted because they were outside the valid range
