Hi.

Welcome to the forum.

Using phrases like it doesn't work gives us very little information. If it worked, you would probably not be here, so to say it is not working just is not helpful.

However, I (and I suspect others) would not be likely to wade through your code. Asking specific questions is is the way to get the best help here and in most other forums.

If I needed to work with fixed-length data, I would use perl's read function instead of the <> syntax:
Code:
       read FILEHANDLE,SCALAR,LENGTH,OFFSET
       read FILEHANDLE,SCALAR,LENGTH
               Attempts to read LENGTH characters of data into variable SCALAR
               from the specified FILEHANDLE.  Returns the number of
               characters actually read, 0 at end of file, or undef if there
               was an error (in the latter case $! is also set). 

-- excerpt from perldoc -f read

On the other hand, if awk works for you, great.

When I am tackling a problem, I usually create a small data set for testing. I would also make sure it was small enough to post in a forum, because posting sample data and expected output is is a good way to attract answers. In your case, I would not post the long records, but I would make up a dataset with lrecl=50 or so, with perhaps 10 records or whatever is a representative sample.

Best wishes ... cheers, drl

URI::Split(3)						User Contributed Perl Documentation					     URI::Split(3)

NAME
URI::Split - Parse and compose URI strings SYNOPSIS
use URI::Split qw(uri_split uri_join); ($scheme, $auth, $path, $query, $frag) = uri_split($uri); $uri = uri_join($scheme, $auth, $path, $query, $frag); DESCRIPTION
Provides functions to parse and compose URI strings. The following functions are provided: ($scheme, $auth, $path, $query, $frag) = uri_split($uri) Breaks up a URI string into its component parts. An "undef" value is returned for those parts that are not present. The $path part is always present (but can be the empty string) and is thus never returned as "undef". No sensible value is returned if this function is called in a scalar context. $uri = uri_join($scheme, $auth, $path, $query, $frag) Puts together a URI string from its parts. Missing parts are signaled by passing "undef" for the corresponding argument. Minimal escaping is applied to parts that contain reserved chars that would confuse a parser. For instance, any occurrence of '?' or '#' in $path is always escaped, as it would otherwise be parsed back as a query or fragment. SEE ALSO
