Description

The first chapter of Course 1 highlights several facts on the use of COBOL on today's era.

With the recent survey conducted by the COBOL Working Group, we may want to take a look at the result of the survey, and incorporate that to the chapter or replace the existing content with updated and cited data from the survey.

Currently listed statements:

COBOL is everywhere. You have probably used an application written in COBOL today. For example, consider the following statistics:

• About 95% of ATM swipes use COBOL code.
• COBOL powers 80% of in-person transactions.
• Every day, COBOL systems handle $3 trillion in commerce.

How pervasive is COBOL? Consider these mind-boggling facts:

• Every day there are 200 times more COBOL transactions executed than there are Google searches.
• There are over 220 billion lines of COBOL programs running today, which equates to around 80% of the world's actively used code.
• 1,500,000,000 lines of new COBOL code are written each year.
