Hi Don..
Apologies for not "specifying" correctly.
1>Well Blank Line would mean spaces and tabs only.
2>Blank records in between "|" delimiter means that the column is NULL (blank as of now) . User has forgot to place the data there.
Example ABCDEFGH|"NULL"|M|"NULL"
"NULL"|XYZABNH|"NULL"|4567344
3>Junk Characters would mean characters other that alphabets or numerical or special characters. Something which is not understandable.
Example ¢'Á|äÃ
"
KJHSAJKHHJJ" or "ABCDEFGH" are examples which I have used instead of proper names.
