                            ======

    By the term of the year 2000, computer will face a unavoidable and 
puzzled issue, the Problem Year 2000. The actual meaning of the Problem 
Year 2000 is that the year more than 2000 will be overflowed in computer
or confused as a year in 19th century, this problem will cause vast of 
computer software which was widely use in key application such as Bank-
ing, Insurance, Accounting, Financing, Manufacturing, to make serious 
mistake, and then to make enterprises which use these software fell 
into trouble. As years pass by, the Problem Year 2000 is on the deadline.

                      Theory of Across 2000
                      =====================

    Here is a kind of application software which has the Problem Year 2000
, it store and process date in format yyyymmdd internally, for convenience
it allowed end-users to input date in format mm/dd/yy, in another word 
people can input two digital year instead of four, but with two digital 
year, computer couldn't accept a date in 21st Century. After the year 2000,
these application system can't run properly, cause computer will treat the 
two digital year 00 inputted by end-users as the year 1900. A lot of such 
application systems have been developed these decade, for example, most of 
application systems developed by dBase,Foxbase,Foxpro,Clipper, Visual Basic
, Delphi and so on have the similar problem. Across 2000 is specially 
designed for these application systems.


    No change to apply various change is the basis of develop Across 2000, 
you can randomly specify a period last 100 year between the year 1000 and 
the year 9900, when computer date comes into the period, Across 2000 will 
automatically add 100 year to the two-digital-year date inputted by end-
users, so you can see, Across 2000 can solve all date problem from 10th 
Century to 99th Century caused by changing century. With Across 2000, 
your application systems can easily pass ninety century, the problem of 
passing century will never disturb you.

    Normally computer process date in such sequence: first, separate the 
inputted date into year-month-day, and then compare the year with one 
hundred, if the year is less than on hundred, computer will accept it as 
a date in 19th century, otherwise computer will treat the date as it's 
original meaning. But if your application system was modified by Across 
2000, the method of processing date will differ completely: suppose you've
already configured a four digital year (century+year) as a start of a 
period of 100 year, after you input a two-digital-year date, computer will 
divide the date into year-month-day also, and then load Across 2000 device 
driver, with the aid of the device driver, computer will compare the inputt
-ed year with the configured year, if the inputted year is less then 
configured year, computer will accept it as a date in the configured 
century, otherwise computer will treat it as a date in the next century.


                       Component of Across 2000
                       ========================

1. Across 2000 explorer
    A set of program used for searching and changing executable file which 
has the Problem Year 2000.

2. Across 2000 device driver
A kind of device driver which be responsible for processing date changing 
and exchanging by demand of application systems. It will be automatically 
added into file conifg.sys once you've run Across 2000 Explorer, and will 
be loaded after you've started your computer. In file conifg.sys, 
expression of the device driver is as bellow:
       Device=c:\p2000\p2000.sys yyyy
yyyy -- a four digital year which indicate a start of a period, yon can 
directly change the year in file conifg.sys if necessary.

                       Advantage of Across 2000 
                       ========================

1. Easy to learn and easy to use, you can solve the Problem Year 2000 
without professional career.
2. Directly modify executable file without sourcecode, Across 2000 is 
the most convenient if you have executable files only or the sourcecode 
is hard to modify.
3. Smart and small, date period can be configured freely to meet your 
demand, Across 2000 can also Across 9000.
4. Cheap, may be the most one.

                      Installation of Across 2000
                      ===========================

1. Start install file, the install file will copy all necessary files to 
specified directory according to your choice.
2. Restart your computer after installation.
3. Run Across 2000 Explorer to search executable file which has the Problem 
Year 2000.
4. Start the application systems modified by Across 2000 and verify if the 
systems can run correctly .

  Note: Only after Across 2000 device driver has been loaded, can you 
utilize Across 2000 to solve the Problem Year 2000.

                       Operation of Across 2000
                       ========================

Run Across 2000 Explorer after installation, then Across 2000 interface 
appears, and now you can choose functions as demand.

Solution
    After pressing 'Solve' button, Across 2000 system will search the 
object files which was specified in 'File' and 'Directory' edit box, and 
find out if the object files have Problem Year 2000  which Across 2000 can 
solve, if the file have other kinds of Problem Year 2000, system will ignore
it.  System will show a message to let you confirm modify if any suspected 
file was found. If you select 'Yes', system will make a source file backup 
which extension name is ._2? (? a digit range 0 to 9), and information 
concerned with modification will be saved in log file, which can be utilized 
to recover source file for future. By default files which extension name is 
'.EXE', '.COM', '.PLB', '.LIB', '.SYS', '.OBJ', '.OVL', '.BIN', '.386', 
'.DLL', '.ESL', '.VXD', '.DRY' can be modified by Across 2000. You can set 
configuration to determine if sourcecode can be backuped and what kind of 
files can be modified. The search operation may take a very long time, 
however yon can press 'Stop' button to stop it.

Scan
    Search files which have every kinds of  Problem Year 2000 without 
modification, The system will show searching progress at the bottom of 
window, and the final result on the middle of window. You can search 
files first before you decided to solve problems detected by Across 2000.

Undo
    Whenever you want to recover files which has been modified, the 
function can do the job automatically according to log file, without 
log file, you can directly copy source backup files to recover.

Stop
   After pressing 'Stop' button, Across 2000 will stop current operation 
and return, waiting for your new selection. 

There are four small buttons at the left corner of explorer window:

Date configuration
   Date period can be specified here, when you input a year in 'From' 
edit box, Across 2000 will calculate the year after 100 years, and show 
the result in 'To' edit box. After configuration, the two-digital-year 
date will be treated as a date within the configured date period instead 
of 1900 to 1999.

Parameters configuration
  Parameter details are listed below:

All file
    Across 2000 will search all kinds of files when the selection is 
enabled, by default system only search files with extension name '.EXE',
' .COM', '.PLB', '.LIB', '.SYS', '.OBJ', '.OVL', '.BIN', '.386', '.DLL',
 '.ESL', '.VXD', '.DRY'.

Backup modified file
   By default, Across 2000 will backup source files before modification, 
the backup file's extension name is '._?' (? a digit range 0 to 9), when 
this selection is disabled, Across 2000 will modify suspected files without 
backup.
  
Log file
    Modification information will be saved in log file, the log file name 
can be assigned here. 

Overwrite log file
    By default, modification information can be added forever into log 
file whenever Across 2000 is running, but with this selection enabled, 
Across 2000 will delete the old log file and create a new one each time 
when it's running. With the old log file overwritten, original files 
modified before may not be recovered , so you should be careful to select 
the function.
