say my url is
http://10.50.1.2/mycgi.pl?records_per_page=10
it'll display 10 lines in the page.
now if you click the link from the main page,
the url is actually,
http://10.50.1.2/mycgi.pl
so you click it, no lines will displayed in the page.
Then you need to click the "submit" to see results.
If i want to see 10 lines by default at the 1st time,
how should i do that ?

Many ways to do it, e.g.
1) make mycgi.pl have a default 'records_per_page' of 10 (or whatever number
you want on the first page).
OR
2) change the link on the main page to point to 'mycgi.pl?records_per_page=
10'

1.ｓｅｒｖｅｒ 方面，每次用户ｓｕｂｍｉｔ时候，同时返回一个当前记录的指针。
这个指针用来跟踪哪１０个记录已经被显示了。作为一个ｐａｒａｍｅｔｅｒ 回到你
的ｐｅｒｌ ｓｃｒｉｐｔ中。
假设你用 ｐｅｒｌ＋ｍｙｓｑｌ
sub get_nth_record{
$nth=$_[0]; // keep user returned pointer
$stmt=$_[1]; // and more params
mysql="SELECT * from myTABLE where conditions limit nth,nth+10";
return mysql_results;
}
^好久不用ｐｅｒｌ了，惭愧
2.if you do it from client side, that will be better.
use javascript. save all the results (if not too many) into an array object.
keep a global value/pointer to save current record. only to display nth 10
records. that is basic.

brother, i know you have been warmhearted to help,
but if if you treat Chinese just like Indians treat Indians,
then you will have more chance to survive in IT in the future.
i got this from linuxquestions,
In your program, check for environment variable QUERY_STRING: if it is empty
, simply act as if it were record_per_page=10
what happened is i was too tired and forget to take care the default for one
of the variables.

Thanks for the advice. Next time I should resist the temptation
that would end in digging a hole for myself when browsing.
