My objective is to prevent bugs that regularly occur and to deliver reports for developers. What I would like to do is: - identify common problems that occur regularly in production and that lead to abends - detect them with some automated routines running on Cobol source code - provide reports with impacted code location, short explanation of the problem and a solution So I'm interesting if you have information about bugs that are interesting to take into account in order to help developer work and to increase the quality of application. I do not have enough experience on this. I ask this question to all experienced developers. Thanks in advance.
