Hi All,
I am very new to the Mainframes world. I am just in the learning stage of it.
I have very general questions about Cobol,JCL,Db2.
I want to know the relation between these three and how are they used in a particular programe from the time of coding the programe till the execution.
Please explain with examples if possible.
Thank you so much,
Shekhar Reddy |

COBOL is a programming language, use mostly for business applications.
JCL is a control language, used only for jobs.
DB2 is a relational database which might be accessed using programs or utilities.
COBOL, as programming language, may include access commands to DB2, which can be identified (mostly) by using the statement "EXEC SQL".
A COBOL program, after compilation, may be invoked using JCL.
