Even if it has been a long time that I programmed in COBOL, I'm know a lot about the language and it's complexities. Cobol requires to work directly with the data, there is no SQL queries. Everything has to be done by hand. It is a language not suitable for tenderfoot.
I'm not a COBOL Developer, I'm a COBOL programmer. There are no COBOL developers.
People that has learned to programm in Visual Environments, with Databases queries will never be able to understand how Cobol works.
