Hi,
Below is the code which is not matching some of the valid data.
c$CD = 'A_TAG_HSSL_LBA_1';
$t=$CD;
if($t1 !~ /A_[A_Z0-9_]+/i)
{
print "$t is not matching\n";
}
else
{
print "$t matches\n";
}

For $CD value A_TAG_HSSL_LBA_1 it is giving "'A_TAG_HSSL_LBA_1' is not matching" as an output while it is matching the regular expression.

When i change the $CD value to 'A_TAG_HSSL_LBAB_1' is says it matches.... Is there any problem with the regular expression....
Please help!!
