fortunately, the system has been set-up such that only one user will be working with one file at a time.

I am afraid the file size is more than 20kb for maxcase

I am curious to know how you pass Hashes of Hashes (HoH) from one page to another. Can you provide little more details?

The html i have shown is only a portion of the complete code.. I may have deleted few unknowingly as I meant to just give a glimpse of what i did. As I mentioned earlier, I read the data file, store the data in AoH, then for the selected page no, I churn out html rows with Varname (which is what you see in anchor tags as the intent was to show the variable name to the user), Min, Value and Max. I generate the html codes using cgi.pm module here are few lines on how I generate the html using cgi.pm :-

AoH is the array of hashes which holds the data read from the flat file

@required will hold the all the array index that corresponds to the selected page. for example, if you take the sample data file I have given, if user selects pagenum as 1 , then I have a logic to store 0 and 1 to @required. If the user selects pagenum as 2, then 2 and 3 are stored in @required. Then, I use that in a for loop to go to each of the array and print the elements I need from the hash.

...
foreach $ii (@required) {
...
..
$query->a( $AoH[$ii]{'VarName'}),
$query->hidden( -name=>'min', -value=>$AoH[$ii]{'Min'}).
$query->a($AoH[$ii]{'Min'}),
...
etc....
