Yes, great software and one of the best features is an ability to read and edit files from other developers.
This GNU Cobol is an exercise in frustration for the Windows user that don't like to use Linux. You either have to use CYGWin and then it will give you an error message when you try to compile something as easy as Hello World. This is utterly ridiculous in the ease of the software.
There are no 4 star reviews.
