It does not matter so much to count included lines by copy....compare to the
figures I got from the net....My question is more to understand if the
Gartner's evaluation is more or less close to the "reality"...200 billions
of Cobol lines!!!
75% of business data is processed in COBOL (Source: Gartner).
There are 180 billion to 200 billion lines of COBOL in use worldwide
(Gartner).
15% of new applications are written in COBOL (Gartner).
Replacement costs for COBOL systems estimated at $25 per line are in the
hundreds of billions of dollars (Tactical Strategy Group).
