how to read file line by line?
Assuming input file like that: 10 15 30.0 10 30 6.0 5 30 4.0 ........... how can I read it, line by line, and discard lines with '15' as a second word? I know that I can read the whole file into a big list and then create a list of records using Select, but this does not help on large files. The required approach is to read in only lines satisfying certain criteria. -- charles loboz to reply: remove please.no.spam from the address
