one more thing I have just tried the following and its working fine
Quote:
echo "1 2 3
2 3 4 5"|while read line
do
echo $line
val=$1
tmp=`echo $val|cut -c 1-4`
tmp1=`echo $val|cut -c 3-6`
echo $tmp $tmp1
done
pass the string as a parameter to string and the values are properly CUT.

YAZ_SCAN(3) 1 YAZ_SCAN(3)
yaz_scan - Prepares for a scan
SYNOPSIS
void yaz_scan (resource $id, string $type, string $startterm, [array $flags])
DESCRIPTION
This function prepares for a Z39.50 Scan Request on the specified connection.
To actually transfer the Scan Request to the server and receive the Scan Response, yaz_wait(3) must be called. Upon completion of
yaz_wait(3) call yaz_error(3) and yaz_scan_result(3) to handle the response.
PARAMETERS
o $id
- The connection resource returned by yaz_connect(3).
o $type
- Currently only type rpn is supported.
o $startterm
- Starting term point for the scan. The form in which the starting term is specified is given by parameter $type. The syntax
this parameter is similar to the RPN query as described in yaz_search(3). It consists of zero or more @attr-operator specifica-
tions, then followed by exactly one token.
o $flags
- This optional parameter specifies additional information to control the behaviour of the scan request. Three indexes are cur-
rently read from the flags array: number (number of terms requested), position (preferred position of term) and stepSize (pre-
ferred step size).
RETURN VALUES
No value is returned.
EXAMPLES
Example #1
PHP function that scans titles
<?php
function scan_titles($id, $startterm)
{
yaz_scan($id, "rpn", "@attr 1=4 " . $startterm);
yaz_wait();
$errno = yaz_errno($id);
if ($errno == 0) {
$ar = yaz_scan_result($id, $options);
echo 'Scan ok; ';
foreach ($options as $key => $val) {
echo "$key = $val ";
}
echo '<br /><table>';
while (list($key, list($k, $term, $tcount)) = each($ar)) {
if (empty($k)) continue;
echo "<tr><td>$term</td><td>$tcount</td></tr>";
}
echo '</table>';
} else {
echo "Scan failed. Error: " . yaz_error($id) . "<br />";
}
}
?>
