Answer / gowthamgyaa

Mainframe can understand only in terms of hexadecimal. Application programming what we coding like COBOL, have to be converted into Hexadecimal. Hence during the stages of compiling, our Programming codes would be link-edited and moved to load library as hexadecimal codes.

Since Load library is a private library[used only by single user], we are using joblib to invoke it.

JCL lib would be used to invoke system libraries like ZOS.PROCLIB.
