RE: Working with binary files storing text data

Here is the situation - explained further.....  We have a piece of
hardware that reads data from wire looms on the factory floor.  The
hardware is monitored by another piece of hardware.  The second piece of
hardware allows us to connect using a UDP socket program to port 1658.  

We have an RPG program that connects to port 1658 using the UDP protocol
(UDPSERVER - thanks Scott for the excellent example).  We are receiving
the data, but it is in binary format.  Each byte of data must be
converted to character data in the end.  These characters then must be
interpreted in a specific manner.

When we receive the data in the RPG program, the first character of the
buffer is visible, but the remainder is not interpreted.  You can see
that there is data there, but it is displayed as blocks.

Any thoughts?

Thanks 

Mike

Hi Mike,

A few things about your message that I'm unclear on:

a) How are you transferring the data? TFTP? NFS? RealAudio? (All of
these 
are file sharing protocols that use UDP to move the data across the 
network.)

b) How are you saving the data to the IFS?  Did you write a program that

does this?  How does it work?  What part of the IFS are you referring
to?

c) How are you trying to open the file in the IFS?  In an RPG program? 
What API does it call?  What parameters do you pass to the API?

d) What happens when it fails?  Do you get an error message?  Do you get

data that you didn't expect?

I can't even begin to offer you code samples since I don't understand
what 
you're trying to do.
