Reply with quote

I have a file containing header and trailor rec. The header starts with BOF - Beginning of file. The Trailor records with EOF - End of file.

In between the header and trailor records exists a set of records which needs to be sorted.

Can you please suggest how do I sort the records existing between the header and trailor record.

In the output file I need the Sorted records along with Header and trailor records. The header record at beginning and trailor at the end.


Input file looks like - 50 bytes lenght

BOF 12/12/06 010101
recrajesh 9845098450
recsantosh 9880066000
EOF count 2

the header records has
BOF - define beginning of file
12/12/06 - creation date
010101 - time of creation
remaining byte are SPACES

The Trailor record has
EOF - End of file
COUNT - Character constant
XX - Number of records , in present case its 2


The records to be sorted Start exists in between these header and trailor record. these records needs to be
1, Sorted based on the number
2. may start with "REC'(which is valid value)
At time it can contain SPACES or JUNK.


I need to sort this out immediately..
