Export/Import procedures

I have created some I/O modules that seemed to be working except in this
instance where I am CHAINing to a logical file and have prefixed the
field names. The found indicator is set on, but the data is not passed
back as I expected. I am in debug and can see where the CHAIN worked but
the prefixed field names do not have any values; however the
non-prefixed field names do have expected values.
Other programs that use I/O modules work and pass data back to the
calling program, but this is the first instance where I needed data in
the prefixed fields passed back rather than just the FOUND indicator.
It seems that the export is working in the global portion of the
programs if there is no prefix.
I must be missing something with the prefix.
Thanks
