Hm...so there's no way to do that without the seek function? This has come up again; here, I need to write characters to a certain position. There isn't some writetowhatever(FILEHANDLE, $variable, NUMCHARS, $offset) function or anything that would make that possible with just one function instead of two or more?

Check perlfunc if you want. But the standard is to seek and then to write or syswrite. (The difference being whether you want to buffer your requests to write. Usually you do. Really.)	[reply]

I think you mean `print` (buffered by default) or `syswrite` (unbuffered)? `write` is not the opposite of `read`	[reply] [d/l]

Gah, I've been playing with Python too much. You're right.	[reply]
