PA_LoadRecord (tableNum)

The routine PA_LoadRecord loads or reloads the current record for the table number tableNum . If there is no current record PA_LoadRecord does nothing.

Loop or loading an unlocked record.

   /*
      waiting the record to be unlocked
      a timeout is used to avoid infinite loop
      a call to PA_Yield MUST BE DONE in such case, to give
      the 4D scheduler time to process other tasks. If this is
      not done, the user will think its computer is frozen.
   */
   void LoadRecordUnlocked(short tNum, long timeOut)
   {
      long   start;
      if(timeOut <= 0)
         timeOut = 60;//default value
   // GetTicks is a routine returns the tick count under Windows and MacOS
      start = GetTicks();
      do
      {
         PA_Yield();
         PA_LoadRecord(tableNum);
      } while ( PA_Locked(tableNum) || ((GetTicks() - start) < timeOut) );
   }
