(g)awk how to preseve white spaces (FS characters) or read a right subpart of $0?

Hi,
I am using gawk (--posix) for extracting some information from something like the following lines (in a text file):

sms_snath_hp_C/CORE BUILD PREREQUISITE:
total 1556
drwxrwxrwx 2 sn sn 4096 2008-06-27 08:31 ./
drwxrwxrwx 13 sn sn 4096 2009-07-22 14:48 ../
-rwxrwxrwx 1 sn sn 15348 2007-05-11 08:37 This is a file name with seven spaces.jar*
-rwxrwxrwx 1 sn sn 22395 2007-05-11 08:37 This is a file name with eight spaces.jar*
-rwxrwxrwx 1 sn sn 73687 2007-05-11 08:37 ibmjcefw.jar*
-rwxrwxrwx 1 sn sn 767101 2007-05-11 08:37 ibmjceprovider.jar*

With regular expressions (pattern matching) I am ignoring all the lines except the ones which are NOT directories with long listing format.

So I consider only:
-rwxrwxrwx 1 sn sn 15348 2007-05-11 08:37 This is a file name with seven spaces.jar*
-rwxrwxrwx 1 sn sn 22395 2007-05-11 08:37 This is a file name with eighteen spaces.jar*
-rwxrwxrwx 1 sn sn 73687 2007-05-11 08:37 ibmjcefw.jar*
-rwxrwxrwx 1 sn sn 767101 2007-05-11 08:37 ibmjceprovider.jar*

Question is: How do I get the file names with preserving the white spaces in between?
Note that the file has no embedded FS character, then it is just $8 and the problem is over. If the file name has embedded multiple FS characters, then I just do not want to concatenate $8 FS $9 FS $10 (etc in a loop) but I also want to have the multiplicity of the FS characters preserved.
(something like that "read v1 v2 v3 v4 v5 v6 v7 fileName" would do).

Thanks.

ifx_fetch_row - Get row as an associative array

SYNOPSIS
array ifx_fetch_row (resource $result_id, [mixed $position]) DESCRIPTION
Fetches one row of data from the result associated with the specified result identifier. Subsequent calls to ifx_fetch_row(3) would return the next row in the result set, or FALSE if there are no more rows. PARAMETERS
o $result_id -$result_id is a valid resultid returned by ifx_query(3) or ifx_prepare(3) (select type queries only!). o $position - An optional parameter for a "fetch" operation on "scroll" cursors: NEXT, PREVIOUS, CURRENT, FIRST, LAST or a number. If you specify a number, an "absolute" row fetch is executed. This parameter is optional, and only valid for SCROLL cursors. RETURN VALUES
Returns an associative array that corresponds to the fetched row, or FALSE if there are no more rows. Blob columns are returned as integer blob id values for use in ifx_get_blob(3) unless you have used ifx_textasvarchar(1) or ifx_byteasvar- char(1), in which case blobs are returned as string values. EXAMPLES
Example #1 Informix fetch rows <?php $rid = ifx_prepare ("select * from emp where name like " . $name, $connid, IFX_SCROLL); if (! $rid) { /* ... error ... */ } $rowcount = ifx_affected_rows($rid); if ($rowcount > 1000) { printf ("Too many rows in result set (%d) <br />", $rowcount); die ("Please restrict your query<br /> "); } if (! ifx_do ($rid)) { /* ... error ... */ } $row = ifx_fetch_row ($rid, "NEXT"); while (is_array($row)) { for (reset($row); $fieldname=key($row); next($row)) { $fieldvalue = $row[$fieldname]; printf ("%s = %s,", $fieldname, $fieldvalue); } printf(" <br />"); $row = ifx_fetch_row($rid, "NEXT"); } ifx_free_result ($rid); ?> PHP Documentation Group IFX_FETCH_ROW(3)
