RE: Another ftp-type question.

Simon,

Thanks for the explanation about FTP. It seems so obvious now.

I did finally find the documentation regarding DDS for LF's; instead of using a search function, I just had to settle down and read until I found the section which you pointed out.

Thanks for your help.

Would you mind giving an example. I've never come across a

how to do so.

There are examples in the IBM documentation. See the InfoCentre.
Start at Database->Programming->Database Programming->Setting up
database files->Describing logical file record formats.

You'll see it discusses the reformatting that is supported by logical
files.

I'm also extremely curious about PUTting an LF on System-A and
being able to read the data residing on System-B. Was I incorrect
when I said that an LF is nothing more than an index, which in and
of itself contains no actual data? Again, I'm asking so I can
learn something new - even if it throws something I thought I knew
into a dustbin.

The concept you are missing is that although FTP is "File Transfer
Protocol" it doesn't transfer files. It transfers data. When you
'point' FTP at a logical file it transfers the data surfaced by that
logical--essentially a remote system copy operation.

This also explains why you can FTP to printer files or direct to
printer ports if you want.

Simon Coulter.
