The government and private companies are scrambling to try to correct
the massive computer glitch known as the "Year 2000 problem."
Unless the problem is fixed, mainframe computers throughout the world may
crash January 1, 2000, because computers, which record the year using only
the last two digits, will be unable to distinguish between the year 2000
and the year 1900. Virtually all mainframe computers are affected by the
problem (which, for the most part, will not affect personal computers).
Correcting what would seem to be a fairly simple problem is actually
enormously difficult, partly because the code is written in a computer language
known as COBOL, which is no longer used and which few computer programmers
know well, and partly because the year appears in about 1 out of every 50
lines of programming, each of which must be corrected. |

Experts estimate it will cost $600 billion to correct the problem in
the United States alone. And correcting the problem will take time. "If
you're not changing code by November of this year," warns one expert,
"you will not get this thing done on time-it's that simple."
No one really knows what the worst-case scenario of the "Year 2000
problem" is, although experts claim it could be very bad indeed. Automated
Teller Machines (ATMs), for example, could fail to function, and banks and
other financial institutions that did not plan ahead could lose all their
records. Federal, state, and local governments could lose data on budgets,
payments due, and income tax liabilities.
Questions
1. Why are the mainframe computers in danger of crashing January 1, 2000?
2. What are some of the problems that may occur as a result of the "Year 2000 problem"? |
