I have a file like below

BUFFALO||14-SEP-09
BUFFALO||20-O
CT-09

BUFFALO||31-JUL-09

Line #1 and Line # 5 are correct.
Line # 4 has jsut a carraige return and that needs to be removed.
Line # 2 the date field has been broken with a carraige return and it has splilled into Line # 3. They both have to be combined.

Can you please help me with a perl script/logic to fix these two issues.

Thank you.
