Hello,
I have a problem while I'm processing my sequence file. The file content
is like this.

I know text files, binary files, random access files, sequential files,
but I've never heard of a sequence file.

Jue,
My most work is to process DNA so I save DNA sequences as a format called
FastA as you've seen before. And you could call my file dna.fasta, the
content is
>seq1
ACGGTC
ACTG
>seq2
CGATCC
ACCTC
>seq3
......
The "seq1" "seq2" "seq3" and "seqx" is the names of these sequences. I can
say, it's a mark. And under "seqx" it's DNA sequences. My point is quite
simple, I wanna extract every sequences as a file saved. I mean I can
extract sequences for dna.fasta and make a single file for every sequences.
There's an example.

From your previous description I thought those were 3 separte files.
Obviously I was wrong.

The usage of each perl function is described in the first line(s) of the
manual page for this function. It doesn't explicitely say "Usage" as in
Unix man pages, but it has the same format:
select FILEHANDLE
Sometimes, if a function is overloaded, there may be additional usages
farther down the page, too, e.g.
select RBITS,WBITS,EBITS,TIMEOUT
