• Subject: If %Open() vs CLOSE(E)

  Which is more efficient: "If %Open()" or CLOSE(E) ?

  I suspect the latter. Here's the scenario.  A file will be opened and 
closed potentially about 1,000 times, pointing to different members.

  Pseudocode:

DO    1000

CLOSE( E )
DLTOVR
OVRDBF FILE() MBR()
OPEN

ENDDO

  The only time the CLOSE will receive an error will be during the first 
CLOSE.  So the question is:  Would one error invocation (under the covers) 
be more efficient than 1,000 If %Open() tests?

  Thanks.
