Memory File Speed

[James Zukowski]

Does anyone know whether it would be faster to PURGE a memory file or CLOSE/reOPEN it? There are 2 keys and relatively few records (<50).

Thanks!

Likely the difference in time would be negligible. 

The CLOSE and the PURGE go through the same logic to free the memory assigned to the records.

The PURGE might be slightly faster simply because of the overhead to free and re-create the internal file header not to mention that the PURGE is a single directive whereas to CLOSE and OPEN sequence consists of two.
