Split Large Files Based On Row Pattern..
Hi all.

I've tried searching the web but could not find similar problem to mine.

I have one large file to be splitted into several files based on the matching pattern found in each row.

For example, let's say the file content:
Code:
MONTH,ACCOUNT_NO,CUSTOMER_NAME,SEGMENT_CODE,COST_CENTER,BILLED_DATE,BILL_FREQ,BILL_START_DATE,BILL_END_DATE,BILLED_RENTAL,BILLED_EARNED,PREVIOUS_BILLED_EARNED,REMAINING_UNEARNED_BALANCE,TOTAL_REVENUE_EARNED

and so on.

Also, I want to retain the heading
Code:

in each file

Thank you very much for helping.
