LANGUAGES

Here let me explain very briefly that mainframes contains four different modules they are as listed below:

• COBOL :- (COMMON BUSSINESS ORIENTED LANGUGE)
• JCL :- (JOB CONTROL LANGUAGE)
• VSAM :- (VIRTUAL STORAGE ACESS METHODS)
• DB2 :- (DATA BASEMANAGEMENT SYSTEM)
• CICS :- (CUSTOMER INFORMATION AND CONTROL SYSTEM)

Combination of all these modules is Mainframes.Don't think that there are so many modules to learn ofcourse you need to learn but they are quiet interesting.This mainframes are different to learn compare to other languages. Just you need to know basics to write a program.I will explain each and every module clearly with example programs.To practice mainframes in home you need to get the mainframes software which are easily available.Just bring that and install in your P.C. So as i said working with programs are quiet different compared to other languages but logics are same.So in further chapters i will explain these modules.
