Gnats 4680: SCT: Expression Slots Allow Input Flags
*** FIX IN RiverWare 5.1 ONLY *** Fixed: 03-09-2009

File: QtSCT/SctModelData.Sim.cpp
Add the 2nd condition (below) to these two methods:

(1) bool SctModelData::flagCanBeSetOnSeriesSlot (SeriesSlot*, char flagCh)
(2) bool SctModelData::valueCanBeSetOnSlot (Slot*, const Date_Time*)

  // Expression slot values cannot be edited
  if (slotPtr->isA (Slot::ExpressionSlotBit)) return (false);
  if (slotPtr->computedByExpr()) return (false);
  //------------------------------------------>>
