Re: Defining datastructure with ExtName/LikeRec

Barbara,

<snip>
EXTNAME and LIKEREC have exactly the
same functionality except that LIKEREC doesn't allow you to add more
subfields. But that's not really a feature, since if you add more
subfields to the EXTNAME structure, the original subfields still exactly
match the I/O buffer.
</snip>

Plus you can't really call it a "feature" if it allows less functionality
than an alternative, can you. Surely you call it a "limitation"... :-)

So are EXTNAME and LIKEREC basically implemented in the same way under the
covers?

Scott pointed out that doing an explicit read into a LIKEREC DS simply moved
the record buffer, whereas doing an implicit read into an EXTNAME DS did a
field-by-field move, but is that the only difference (under the covers)?
