- 09 Daily Script Master now saves to and loads from the backend (sample rows removed), with Drop to correct a wrong rate. - Purchase Entry takes the rate (NAV for a mutual fund) from the newest Daily Script Master rate on or before the deal date, shows which rate was used, warns when the rate entered is outside the day's low-high, and clears the rate when the script has none. - Broken-period interest paid to the seller is debited to expense GL 500606 instead of Interest Receivable (RBI UCB Investment Directions, para 152, confirmed by Jitendra Sir); Interest Entry labels it so.
