Practical experiences with automatic repair of syntactical errors or syntactical error repair in the DAS compiler

In this note some practical experiences with error repair methods are discussed. Two methods, a continuation method designed in Karlsruhe and the method used in the Berkeley PASCAL compiler, have been investigated for use in a compiler for an Ada subset, the DAS (Delft Ada Subset) compiler.The method finally applied is the natural synthesis of those two methods.
