in reply to Re^4: Reading tab/whitespace delimited text file
in thread Reading tab/whitespace delimited text file

Because in order to find the length of each field in this crazy format, it relies on the length of the header field to determine the length of the value fields.

But, (uniquely) in the case of:

CELL
LUC325C

[download]

The header field is shorter than the value field.

And as that record pair was not a part of the sample you showed when you originally asked this question, the code does not cater for it.

Adding this line to the code above will allow it to handle that part of the data format:

    $tmpl =~ s[\d+$][*];

    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 . . .

      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 ..???
