Re: writing large single record stream file



fixed

According to manuals, it was increased to approx 1TB with V5R3, currently
the same with V7R1.

I think the original question was how many bytes can I write at a time from
an RPG program, not how big the file can be.

I thought about it more and it occurred to me that number is 2,147,483,647
bytes through a pointer because number of bytes to write is an integer and
as Jon said through a RPG variable 16MB.

That was a V6R1 limit.
Several limits were increased with V7R1
Either 256 gb or 512 gb , might be higher 1 tb.

But if your program is tereaspace enabled, you allocate storage and you
write to the IFS though a pointer aren't you talking tereaspace being a
limit?

But as earlier poster mentioned. It doesn't really matter. You can write
one byte at a time or 10 million. You can write a single record in one
write or you can write it in a dozen writes. The IFS doesn't care. It is
just streams of bytes. The only reason it really matters and that is not
much is efficiency.

No so in any release from V6 onwards - at V6 the size went up to 16Mb.

What are the limits of writing a single stream record from RPGLE?
I need to write EDI unwrapped stream file, possible 10 to 100 meg
(it's
a monthly file to a government agency). Am using program based on
Scott Klement's IFS samples, currently writing one record per segment,
but have not figured out how to append each segment to a single
record, and what the limits will be. File is much larger than a single
field can hold. Looking for a sample.
