INTERFACE Debug;

PROCEDURE Out(t : TEXT; minLevel : CARDINAL := 10);
PROCEDURE S(t: TEXT; minLevel : CARDINAL := 5);
PROCEDURE Warning(t : TEXT);
PROCEDURE Error(t : TEXT);
PROCEDURE UnNil(text : TEXT) : TEXT;

 apart from these procedures, the debug level is also set from the
   env. variable DEBUGLEVEL 


 if nothing else, it defaults to zero 


PROCEDURE RaiseLevel(newLevel : CARDINAL);
PROCEDURE LowerLevel(newLevel : CARDINAL);
PROCEDURE SetLevel(newLevel : CARDINAL);
PROCEDURE GetLevel() : CARDINAL;

END Debug.
