Introduction:


COBOL is an acronym for COmmon Business Oriented Language. COBOL is a high-level programming language very first developed by CODASYL Committee (Conference on Data Systems Languages) in early of 1960’s (First COBOL compiler was implemented in the same year). In the later years, so many revisions and modifications applied on the initial version of COBOL. COBOL primarily developed for business, finance and administrative system needs and mostly using in banking, insurance applications and government sectors. COBOL is mostly used language in the mainframe system to implement the changes to get the objective.


Audiences:


Readers who may have or not having mainframe knowledge.


Objective:


The tutorial is intended for the readers with no previous programming or computer science experience as well as for those with some computing background. In the tutorial, all the topics are covered with in depth description and can understandable by anyone who had minimum/no computation background.


Prerequisites:


There are no prerequisites to learn COBOL language. Having the computation background will be an advantage in understanding the concepts a bit easy. Without having computation background, it is a bit time taking to understand the concepts and need to go through the topic more than once to understand clearly.
