Fiction, Fantasy, and Fact:

"The Mad Scramble for the Elusive Silver Bullet . . . and the Clock Ticks Away."

Wayne Anderson

November 7, 1996

The year 2000 is practically around the corner, promising a new era of greatness and

wonder . . . as long as you don't own a computer or work with one. The year 2000 is bringing a

Pandora's Box of gifts to the computer world, and the latch is slowly coming undone.

The year 2000 bug is not really a "bug" or "virus," but is more a computer industry

mistake. Many of the PC's, mainframes, and software out there are not designed or

programmed to compute a future year ending in double zeros. This is going to be a costly "fix"

for the industry to absorb. In fact, Mike Elgan who is the editor of Windows Magazine, says " . .

. the problem could cost businesses a total of $600 billion to remedy." (p. 1)

The fallacy that mainframes were the only machines to be affected was short lived as industry

realized that 60 to 80 million home and small business users doing math or accounting etc. on

Windows 3.1 or older software, are just as susceptible to this "bug." Can this be repaired in

time? For some, it is already too late. A system that is devised to cut an annual federal deficit to

0 by the year 2002 is already in "hot water." Data will become erroneous as the numbers "just

don't add up" anymore. Some PC owners can upgrade their computer's BIOS (or complete

operating system) and upgrade the OS (operating system) to Windows 95, this will set them up

for another 99 years. Older software however, may very well have to be replaced or at the very

least, upgraded.

The year 2000 has become a two-fold problem. One is the inability of the computer to

adapt to the MM/DD/YY issue, while the second problem is the reluctance to which we seem to

be willing to address the impact it will have. Most IS (information system) people are either

unconcerned or unprepared.

Let me give you a "short take" on the problem we all are facing. To save storage space

-and perhaps reduce the amount of keystrokes necessary in order to enter the year to date-most

IS groups have allocated two digits to represent the year. For example, "1996" is stored as "96"

in data files and "2000" will be stored as "00." These two-digit dates will be on millions of files

used as input for millions of applications. This two digit date affects data manipulation,

primarily subtractions and comparisons. (Jager, p. 1) For instance, I was born in 1957. If I ask

the computer to calculate how old I am today, it subtracts 57 from 96 and announces that I'm 39.

So far so good. In the year 2000 however, the computer will subtract 57 from 00 and say that I

am -57 years old. This error will affect any calculation that produces or uses time spans, such as

an interest calculation. Banker's beware!!!

Bringing the problem closer to the home-front, let's examine how the CAPS system is

going to be affected. As CAPS is a multifaceted system, I will focus on one area in particular,

ISIS. ISIS (Integrated Student Information System) has the ability to admit students, register

them, bill them, and maintain an academic history of each student (grades, transcripts, transfer

information, etc.) inside of one system. This student information system has hundreds and

hundreds of references to dates within it's OS. This is a COBOL system accessing a ADABAS

database. ADABAS is the file and file access method used by ISIS to store student records on

and retrieve them from. (Shufelt, p.1) ADABAS has a set of rules for setting up keys to specify

which record to access and what type of action (read, write, delete) is to be performed. The

dates will have to have centuries appended to them in order to remain correct. Their (CAPS)

"fix" is to change the code in the Procedure Division (using 30 as the cutoff >30 century = "19"

30) then it can

be assumed that you are referring to a year in the 20th century and a "19" will be moved to the

century field. If the year is less than 30 (absolutely necessary, ISIS will add a field and a superdescriptor index in order to keep record

retrieval in the order that the program code expects. The current compiler at CAPS will not

work beyond the year 2000 and will have to be replaced. The "temporary fix" (Kludge) just

discussed (30) will allow ISIS to operate until the year 2030, when they hope to have

replaced the current system by then.

For those of you with your own home computers, let's get up close and personal. This

problem will affect you as well! Up to 80% of all personal PCs will fail when the year 2000

arrives. More than 80,000,000 PCs will be shut down December 31, 1999 with no problems.

On January 1, 2000, some 80,000,000 PCs will go "belly up!" (Jager, p. 1) These computers

will think the Berlin Wall is still standing and that Nixon was just elected President! There is

however, a test that you can perform in order to see if you are on of the "lucky" minority that do

not have a problem with the year 2000 affecting their PC.

First, set the date on your computer to December 31, 1999. Next, set the time to 23:58

hours (if you use a 24 hour clock (Zulu time)) or 11:58 p.m. for 12 hour clocks. Now, Power Off

the computer for at least 3 to 5 minutes. Note: ( It is appropriate at this time to utter whatever

mantras or religious chants you feel may be beneficial to your psyche ). Next, Power On the

computer, and check your time and date. If it reads January 1, 2000 and about a minute or two

past midnight, breathe a sigh of relief, your OS is free from the year 2000 "bug." If however,

your computer gives you wrong information, such as my own PC did (March 12, 1945 at 10:22

a.m.) welcome to the overwhelming majority of the population that has been found "infected."

All applications, from spreadsheets to e-mail, will be adversely affected. What can you

do? Maybe you can replace your computer with one that is Year 2000 compatible. Is the

problem in the RTC (Real Time Clock), the BIOS, the OS? Even if you fix the hardware

problem, is all the software you use going to make the "transition" safely or is it going to corrupt

as well?!

The answers to these questions and others like them are not answerable with a yes or a

no. For one thing, the "leading experts" in the computer world cannot agree that there is even a

problem, let alone discuss the magnitude upon which it will impact society and the business

world. CNN correspondant Jed Duvall illustrates another possible "problem" scenario. Suppose

an individual on the East Coast, at 2 minutes after midnight in New York City on January 1,

2000 decides to mark the year and the century by calling a friend in California, where because of

the time zone difference, it is still 1999. With the current configurations in the phone company

computers, the NewYorker will be billed from 00 to 99, a phone call some 99 years long!!! (p. 1)

What if you deposit $100 into a savings account that pays 5% interest annually. The

following year you decide to close your account. The bank computer figures your $100 was

there for one year at 5% interest, so you get $105 back, simple enough. What happens though, if

you don't take your money out before the year 2000? The computer will re-do the calculation

exactly the same way. Your money was in the bank from '95 to '00. That's '00 minus '95, which

equals a negative 95 (-95). That's -95 years at 5% interest. That's a little bit more than $10,000,

and because of the minus sign, it's going to subtract that amount from your account. You now

owe the bank $9,900. Do I have your attention yet??!!

There is no industry that is immune to this problem, it is a cross-platform problem. This

is a problem that will affect PCs, minis, and mainframes. There are no "quick fixes" or what

everyone refers to as the "Silver Bullet." The Silver Bullet is the terminology used to represent

the creation of an automatic fix for the Yk2 problem. There are two major problems with this

philosophy. First, there are too many variables from hardware to software of different types to

think that a "cure-all" can be found that will create an "across-the-board" type of fix. Secondly,

the mentality of the general population that there is such a "fix" or that one can be created rather

quickly and easily, is creating situations where people are putting off addressing the problem due

to reliance on the "cure-all." The " . . . sure someone will fix it." type attitude pervades the

industry and the population, making this problem more serious than it already is. (Jager, p. 1)

People actually think that there is a program that you can start running on Friday night . . .

everybody goes home, and Monday morning the problem has been fixed. Nobody has to do

anything else, the Yk2 problem poses no more threat, it has been solved. To quote Peter de

Jager,

"Such a tool, would be wonderful.

Such a tool, would be worth Billions of dollars.

Such a tool, is a na ve pipe dream.

Could someone come close? Not very . . .

Could something reduce this problem by 90%? I don't believe so.

Could it reduce the problem by 50%? Possibly . . . but I still don't believe so.

Could it reduce the workload by 30%? Quite likely."

(p. 2)

Tools are available, but are only tools, not cures or quick fixes.

How will this affect society and the industry in 2000? How stable will software design

companies be as more and more competitors offer huge "incentives" for people to...
