troubleshooting Question
efficiently manipulating records (line) in file
Hi all,
I am trying to implement an order database, which stores records (typically ~500records) in line.
e.g.
order: 1 [type: 1; date: xxxxx; price: $xxx]
order: 2 [type: 4; date: xxxxx; price: $xxxxx]
order: 3 [type: 3; date: xxxxx; price: $xx]
..
order: x [type: 3; date: xxxxx; price: $xxxxxxx]
I would like to efficiently alter the content for example line #2, without reading all records into an array of order structure. How can I do this?
Cheers,
hl
