Scott,

Good question.  Is the following a valid test?

In my estimation that is less than half the size.  Sure would be a nasty
thing to free up half your disk space.  I remember back in the dark ages
when we were estimating disk space in our migration from the S/36 to the
AS/400.  The amount of space that source physical files consumes is
astronomical.  Don't try to convince me that this space is needed by the
date changed.  There is no way that would eat up more than twice the space
used by the actual code.  Now, I do like that date changed though - but
something else is sucking up disk space like a hoover.

Why do you think that the IFS is "SO inefficient a user of space"?

It seems to me that the fixed-length source member is inefficient, since
all the blank characters at the end of every line of text are wasted in a
fixed-length system.

So, I'm baffled by your statement.  Is there something about the IFS that
I don't know?  Something that makes it waste even more space than that?
