Micros Systems Inc. said that expanding sales of its line of computerized sales registers and information systems for the hospitality industry boosted earnings to $9.9 million, or 58 cents a share, in the quarter ended June 30. That was 60.5 percent over last year's fourth-quarter profit of $6.1 million (36 cents).

The 1998 quarterly results included a pretax charge of $2.2 million, or 8 cents a share, following Micros's closure of its European headquarters in Munich.

The Beltsville company posted record sales and per-share earnings both for its fiscal fourth quarter and the 1999 fiscal year ended in June. Quarterly revenue totaled $102.7 million, up from $83.3 million in the 1998 quarter; for the 1999 fiscal year, revenue was $335.1 million, up from $280 million the year before.

* Digene Corp., a Beltsville-based manufacturer of biomedical testing products, said it lost $2.7 million, or 19 cents a share, in its fiscal fourth quarter and $9.3 million (65 cents) for the 1999 fiscal year. Both the quarterly and annual results were sizable improvements over 1998, when the company lost $6.7 million in the fourth quarter and $14.1 million for the year.

Revenue in the June quarter totaled $5.1 million, a 53.7 percent increase over the same period a year earlier, led by increased sales of Digene's RNA- and DNA-based screening products for cervical cancer and its tests for viruses in the blood. Fiscal year revenue rose 45.5 percent, to $17.5 million.
