RE: [abc-users] problem : "Bad class file" producing .class file from the .ppg file

Well, here you got something wrong. PPG is a parser generator, i.e. it generates a Java *source* file containing the parser for the grammar you pass it. By stating "-o Grm.class", you simply rename this file (which should have the name Grm.java actually) to Grm.class. I am sure that if you had had a look at the file with an editor you would have found out that it's actually a Java source file.
