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


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


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


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


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


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


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


unconcerned or unprepared.

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


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


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


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


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


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


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


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


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


"fix" is to change the code in the Procedure Division (using 30 as the cutoff

>30 century = "19"

<30 century = "20"). In other words, if the year in question is greater than

30 (>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 (<30) then it will move a "20" to

the century field. If

absolutely necessary, ISIS will add a field and a superdescriptor index in order to keep


retrieval in the order that the program code expects. The current compiler at CAPS will


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

(Kludge) just

discussed (<30 or >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


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


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


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


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


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


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


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


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


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


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


equals a negative 95 (-95). That’s -95 years at 5% interest. That’s a little bit more than


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


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


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


"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

"jump ship"

and come work for them on their problems!? Cash flow problems will put people out of

business. Computer programmers will make big bucks from now until 2000, as demand

increases for their expertise. What about liability issues that arise because company

"A" reneged

on a deal because of a computer glitch. Sue! Sue! Sue! What about ATM lockups, or credit


failures, medical emergencies, downed phone systems. This is a wide spread scenario


the Yk2 problem will affect all these elements and more.

As is obvious, the dimensions to this challenge are apparent. Given society’s reliance on

computers, the failure of the systems to operate properly can mean anything from minor

inconveniences to major problems: Licenses and permits not issued, payroll and social


checks not cut, personnel, medical and academic records malfunctioning, errors in banking


finance, accounts not paid or received, inventory not maintained, weapon systems

malfunctioning (shudder!), constituent services not provided, and so on, and so on, and so


Still think you’ll be unaffected . . . highly unlikely. This problem will affect

computations which

calculate age, sort by date, compare dates, or perform some other type of specialized

task. The

Gartner Group has made the following approximations:

At $450 to $600 per affected computer program, it is estimated that a medium size company


spend from $3.6 to $4.2 million to make the software conversion. The cost per line of code


estimated to be $.80 to $1. VIASOFT has seen program conversion cost rise to $572 to


ANDERSEN CONSULTING estimates that it will take them more than 12,000 working days to

correct its existing applications. YELLOW CORPORATION estimates it will spend

approximately 10,000 working days to make the change. Estimates for the correction of this

problem in the United States alone is upward of $50 to $75 Billion dollars.

(ITAA, p. 1)Is it possible to eliminate the problem? Probably not, but we can make the transition

much smoother with cooperation and the right approach. Companies and government agencies

must understand the nature of the problem. Unfortunately, the spending you find for new

software development will not be found in Yk2 research. Ignoring the obvious is not the

way to

approach this problem. To assume that the problem will be corrected when the system is

replaced can be a costly misjudgment. Priorities change, development schedules slip, and

system components will be reused, causing the problem to be even more widespread.

Correcting the situation may not be so difficult as it will be time consuming. For

instance, the Social Security Administration estimates that it will spend 300 man-years


and correcting these date references in their information systems – systems representing a

total of

30 million lines of code. (ITAA, p. 3) Common sense dictates that a comprehensive


plan be developed to address the more immediate functions of an organization (such as


pay benefits, collect taxes, or other critical organization functions), and continue from

there to

finish addressing the less critical aspects of operation. Some of the automated tools may

help to

promote the "repair" of the systems, such as in:

* line by line impact analysis of all date references within a system, both in terms of

data and


* project cost estimating and modeling;

* identification and listing of affected locations;

* editing support to make the actual changes required;

* change management;

* and testing to verify and validate the changed system.

(ITAA, p. 3)

Clock simulators can run a system with a simulated clock date and can use applications


append or produce errors when the year 2000 arrives while date finders search across

applications on specific date criteria, and browsers can help users perform large volume


inspection. As good as all these "automated tools" are, there are NO

"Silver Bullets" out there.

There are no quick fixes. It will take old fashioned work-hours by personnel in order to


this "rollover" smooth and efficient.

Another area to look at are the implications for public health information. Public health

information and surveillance at all levels of local, state, federal, and international

public health

are especially sensitive to and dependent upon dates for epidemiological (study of disease

occurrence, location, and duration) and health statistics reasons. The date of events,


between events, and other calculations such as age of people are core epidemiologic and


statistic requirements. (Seligman, p. 1) Along with this, public health authorities are


dependent upon the primary data providers such as physician practices, laboratories,


managed care organizations, and out-patient centers etc., as the source for original data


which public health decisions are based. The CDC (Centers for Disease Control and


for example, maintains over 100 public health surveillance systems all of which are


upon external sources of data. (Issa, p. 5) This basically means that it is not going to


sufficient to make the internal systems compliant to the year 2000 in order to address all

of the

ramifications of this issue. To illustrate this point, consider the following scenario: in


2000, a hospital sends an electronic surveillance record to the local or state health


reporting the death of an individual who was born in the year "00"; is this

going to be a case of

infant mortality or a geriatric case??

Finally, let’s look at one of the largest software manufacturing corporations and see what

the implications of the year 2000 will be for Microsoft products. Microsoft states that


95 and Windows NT are capable of supporting dates up until the year 2099. They also make


statement however:

"It is important to note that when short, assumed dates (mm/dd/yy) are entered, it is
