RE: [MI400] unknown block length

[Jim Langston <jlangston@xxxxxxxxxxx>]

On a PC the way to handle this is to read the file byte by byte when you
don't know the length.  I'm not sure how you're reading this file, what
instructions you're using, but there are also similar ways around it.  If
you can get the file length, you won't have a problem of course, as you
could read your 10000 bytes til you see you can't read that much, then read
the number of bytes available.

I'm not real familiar with MI and what it can do, but have a bit of
familiarity with binary PC files.  Does MI give you the record number you're
own?  If so, why not save the record number, read your 10000 bytes until you
receive CVP5001, then position back to the last valid record number you read
and read byte for byte until you get CVP5001 again.

If MI is not capable of this, perhaps you could call the C file I/O APIs to
do it for you.

HTH.

Folks,
Problem:  a file is uploaded (binary) from a PC.
I need to read it in MI to parse out the data.
The size of the file is not known, I need to read until
the end. I define a record size of (say) 10000 and
start reading. I get the CVP5001 exception as usual
at the end of the file, but the last (incomplete) block
I don't get. How to get it?
