I am new to this forum. This is my first post ever. Any help is appreciated. I have an input file with 500k records. The length of the file is 300 bytes. There is a 6 digit broker code(stock broker) and an 8 digit account code(associated with the broker) in the file. There are records with one broker with one account and one broker with multiple accounts. I need to pick only 100k records covering all the brokers.
Input data:
A/C no. Broker #
02092849 020999
08000010 080102
08000011 080102
08005213 080102
.................................
............. 500k rows
Output data:
02092849 020999
08000010 080102
................................
............ 100k rows |

| You mean you need the first 100k records with unique broker codes? |

| There are around 13,000 broker codes in the file. So I need 100k records that covers all 13,000 brokers. So around 7 duplicate accounts for every broker. The important thing is the output file should have all broker codes. |

with one pass of data You might get
13000 * 7
or
13000 * 8
assuming that every broker has at least 7 or 8 accounts
if some brokers have less accounts noo way to extract more from the others
search for GROUP/RESTART/SEQNO
and select for output only the records with a SEQNO less than 7 or 8
quite a few similar samples around |

then You cannot have with SORT
You will have to adjust for differences
You MUST write two PROGRAMS
the first one to count
the second one to extract
100000 / 13000 ==> 7.69.....
You will have to extract in some cases 7 in some other 8
and You must take into considerations if a broker has less than 7 accounts |
