I use JCL Project Analyser to see what units are used in my project, in order to 'clean' it. But, for big projects, I don't really see the dependencies beause I see the units names but not where they are used. I used Map file but with no success. Is there any free tool for having used units AND where they are used ? I tried GExpert Project Dependancies without succes : Example : I have JCLInifiles in Project Analyser but I don't see it in GExpert Project Dependancies.
