JCL_Factory
===========

This project is called JCL_Factory. Here we will use Java to implement JCL parser which will be used to check JCL format and create a JCL scripts aim to simplify the process of writing JCL scripts and help beginners get started with JES.
JCL is short for Job Control Language. 
For each job you submit in mvs. You need to tell the JES(Job Entry Subsystem) where the essential dataset is. You can use JCL to convey information above to the JES using JCL.

This project is essential because there are less engineers who have mainframe skill while most of business transactions are running on mainframe.So the maintainance of these code is much more complicated than before.
And This will assist operation guys to run jobs even though they don't know too much about the mainframe.

Job Control Language may differ in different z/OS release. Here we will support JCL in z/os 1.13
