Making binary files question



Is it possible with mivascript to create various kinds of binary files
not related to DBF files? I've been experimenting with midi files
without any success.

The experiment is basically this- I MvIMPORT a midi file and then
MvEXPORT the data as it comes in to another file to see what happens.
What happens is that the new file is not even close to being the same as
the old.

Any ideas about how one could mix together custom binary files with miva
script? I notice that PHP can do stuff like fseek, fwrite, etc, that
lets the developer do some low level file stuff.

Appreciate any ideas at all about this.

Thanks-

Scot

Dear Scott, not an answer but a plea: I use a mail client which shows
threading, you evidently do not.
So because you clicked "reply" to an existing message then wiped
everything, I still see your message as a reply to James' post about job
vacancies, to which it is not the least related. The reason: there is a
header which you cannot delete from your mail client's UI, in-reply-to:
with the messageid of James' post.
So please set up miva-users@miva.com as a contact, and when you want to
start a new thread, use compose, not reply.

I've decided to post this to the list, as you are not the only person
guilty of it.
(Someone will now search the archives and probably find a time where I've
done it myself :-)

Making binary files question



Hi Scot,

(Copernicus) James released a pretty neat library for handling binary files.
I don't know if they can help you (or if you did not already use them), but
if not, you should definitely take a look at them. You can find them at the
open source section of his website (

Ah, thanks for letting me know that. I can never remember what email
address to send a group message to, so I just find one and click "reply
all" and delete the subject and message- didn't think about the headers!

Thanks for the tip! I completely forgot James released that thing-
looks like it will do what I'm looking for. (insert Burns "excellent" here)

Making binary files question



You do not need any external library at all. Plain old MvEXPORT works just
fine for exporting any kind of data:

<MvEXPORT FILEfile" FIELDS="l.null,l.null" DELIMITER="{binaryData}">

There is no limit for the binary data passed through the delimiter.

As for importing - I would suggest updating to the newly released v5 and
using the file_read() function.

Hello Ivo,

But they have not released the compiler to us general public coders yet.

Easy help: just compile the script with the old one. To suppress the error
about missing function, simply call it in MvDO call to self:

<MvDO FILE="test.mvc" NAME="l.ret"
VALUE="{file_read('test.bin','data',g.var)}">


In the same way you can use any other new functions.

Making binary files question



So using Ivo's method, does anyone have any suggestions about how I
would go about writing the hex string:

4D 54 68 64

as binary data to a file?

I've tried the MvEXPORT method below and assigned the "binarydata"
variable with the string above, but it just goes in as the string.

This is new ground for me, so any suggestions are appreciated.

chain them together using asciichar's with the decimal equivelent?

Making binary files question



Yeah, Bill (aka aGorilla) is very right. In this specific case it would be

<MvEXPORT FILE="file" FIELDS="l.null,l.null" DELIMITER="DThd">

In fact your example is no binary data at all, rather just the printable
characters 'DThd'.

I'd recommend using an ASCII table or writing a simple function for the
conversion - there are some tricks on my website for hex conversion too.

Silly me for not going to Ivo's site first!

Thanks you guys, I'm feeling stupid today for some reason so your
insights are appreciated.

Making binary files question



I've almost got this working, but two problems have risen up that I'm
not sure how to deal with.

The first is a big one- I can't get asciichar(0) or asciichar('0') to
write to the file as hex 00 (some sort of spacer or null).

The other is that the end of the file turns out to always be hex 0A -
I'd like to somehow be able to control whatever is at the end of the file.

I made this to test what works when trying to write a binary file using
the method below:

<MvWHILE EXPR = "{l.index LE 255}">
<MvASSIGN NAME = "l.export" VALUE = "{ l.export $ asciichar(l.index)}">
<MvASSIGN NAME = "l.index" VALUE = "{ l.index + 1 }">
</MvWHILE>

Everything is written to the file correctly except for hex 00 and the
last character which is hex 0A.

Any ideas?

Scot
