### 4/5 — Great app package for beginners

*2016-04-04, version 2.0*

I am taking COBOL in college and the teacher doesn't use a book as he feels it doesn't teach you real world programming styles. This app is great for being able to look up he JCL statements needed and to help you understand what they are doing and how to use them.
