Marcos Sebastián Uslenghi requested PLSQL (Oracle) support:

Add PLSQL highlighting support.
Example:

DECLARE 
   v_renglon NUMBER := 1;
 BEGIN
    GO_BLOCK('GRILLA');
    FIRST_BLOCK;
    LOOP
      :grilla.renglon := v_renglon;
      EXIT WHEN :SYSTEM.LAST_RECORD = 'TRUE';
      v_renglon := v_renglon + 1;
      NEXT_RECORD;
   END LOOP;
 END;

The uppercase are reserved words. I know PLSQL and any help you need I'm at your disposal
