RE: Member Names

[rob@xxxxxxxxx]

1)  You are not creating, or clearing, a physical file member to store the
list.  There is less overhead to a user space.
2)  You don't have to break out of RPG, or call QCMDEXC (or it's brethren)
to execute a DSPFD
3)  All input from the userspace can be sped up by using pointers (don't
use QUSRTVUS) versus record i/o

I haven't time clocked it.  But sooner or later you really should use the
list API's.  And this is such a simple one.  For samples on how to use the
list API's check out:

Not that I detest fast acting code or anything <g>, but how much faster can
I retrieve all of the member names in, say, a 100 member file by using the
API?  How about a 5 member file?  I'm sure it's faster, but at what point
does the interactive response time difference start to pay off?
