Vernon,

there is no such thing as currencyCode>USA</currencyCode> *LOL*

Michael - check the post I just sent - Henrik's point is well taken - so
if you can make those search strings unique enough, you are fine - and I
gave you a technique that is very nice - we're using it here in production.

You might have to do things like replace <currencyCode>EUR</currencyCode>
with <currencyCode>USA</currencyCode>, etc.

Good point Henrik...thanks!

scan and replace is a bad method!

an IFS file is a large string of data, XML is a data structure

you may have <currencyCode>EUR</currencyCode>

you may have <text>the price is in EUR</text>

you may have <price currencyCode="EUR">12.50</price>

replacing EUR blindfolded may have large impact!

Looks OK - but I'm not sure the risk and lack of flexibility is worth
it.

Personally I'd always do an update-by-copy.

And therein lies the rub. The text that I want to change could be the

size as what I want to replace it with, but the sizes could be

different. A

better way of saying that is that I may have to replace 10 bytes with

10

bytes, or 15 bytes with 15 bytes, but I won't have to replace different
sizes. I won't know what the size is until I read the file.

So, would something like this work?

open...
read into buffer...
use %scan to search buffer and locate text to change...
use lseek to position to that location...
use write to change the file at that location (for a certain number of
bytes)...
close...

You can position to a particular byte of your file using the lseek()

API

Once positioned, the write() API will overwrite bytes at that position
(for the length specified on the call to write API)

Is that what you're asking? {There weren't actually any questions in

your

post.)

I need to update data in a stream file located in ths IFS (or on a

file, and then delete/rename I guess, but I want to update in place.

I

don't want to use any procedures that add a CRLF. I'm thinking of

using

read() and write(), but I'm not sure how to handle the update.

Probably

pretty simple. Thanks!
