It's not the programming language that counts it that the environment
that guarantees transactions - In the case of IBM it's call CICS
(Customer Information Control System) which supports on-line transaction
processing. It makes sure that when you move money from one bank account
to another it either complete of fails - there is no other outcome.
This is very difficult to do in a distributed environment.
COBOL was a transaction based system used for batch record processing.
There is so much COBOL around that it is cheaper and better to keep it -
it is fit for purpose, more so than any other language.
