RE: Efficient Code

Icbw, but my understanding is that the system creats implicit *ACCPTH
sharing automatically, regardless of which order the *LF were created.  ?
Pretty sure it used to, but that's iirc.

|
| A
| A, B
| A, B, C
| A, B, C, D
|
| And you created them in that order you'll have 4 indexes, but if
| you created
| them in the reverse order you'll have one. _BIG_ performance
| difference. It
| can be worth it to examine the logicals for index sharing
| possibilities too.
