in thread Reading tab/whitespace delimited text file

Thank you soooo much for helping .. i'm a newbie to perl and figuring out everything as i go on ...
The code works perfectly ..!!!!! However , while this works for a sample data , when i use it parse the actual text file , it behaves weirdly .. This is what i get for the sample data :

{ AWOFFSET => 5, BQOFFSET => 3, BQOFFSETAFR => 3, CAND => "BOTH", CELL => "LUC325C", CELLR => "LUC232A", CS => "NO", DIR => "MUTUAL", HIHYST => 5, KHYST => 3, KOFFSETN => "", KOFFSETP => 0, LHYST => 3, LOFFSETN => "", LOFFSETP => 0, LOHYST => 3, OFFSETN => "", OFFSETP => 0, TRHYST => 2, TROFFSETN => "", TROFFSETP => 0, } Press any key to continue . . .

And this is what i get when i execute it on a text file :
{ CELL => "LUC325C" } { BOTH => "", LUC325B => "", MUTUAL => "", NO => "" } {} { BQOFFSETAFR => "", HIHYST => 5, LOHYST => "3 0", OFFSETN => "", OFFSETP => 3, } { BOTH => "", LUC116A => "", MUTUAL => "", NO => "" } {} { BQOFFSETAFR => "", HIHYST => 5, LOHYST => "3 0", OFFSETN => "", OFFSETP => 3, } { BOTH => "", LUC204A => "", MUTUAL => "", NO => "" } {} Press any key to continue . . .

Any idea as to why this behaves differently for the same set of data ?????

    I'll need to see both the exact code you are using and the exact datafile. (I'll /msg you my email id.)

      Why does the original code behave differently when i use the while(<FILEHANDLE>) loop as a file handle to read a particular section of code(say between line 2-10) instead of using EOF ..???

        Because while( <DATA> ) { reads and discards a line each time it is executed. And that line contains a header (or data) that is required.

        If you need to skip 29 lines, do so before entering the while loop:

        <DATA> for 1 .. 29; until( eof( DATA ) ) { ...

        And to exit the loop after the 40th line has be read:

        until( eof( DATA ) ) { last if $. == 40; ...
