USE mytable IN SELECT([mytable])
If it's not USED the SELECT() function returns the equivalent of the next
available workarea. If the assumption is that you just want that table
open, this eliminates any amibiguity. Of course as you've pointed out, if
another user or process has an exclusive lock on the table, you'll still
get some kind of file access error. Yes, there's some overhead to
reopening the table but there's also overhead to checking to see if it is
already in use, so as Uncle Ted would point out, you have to test that in
your application environment to determine if that overhead is meaningful.
You can also wrap your USE statements in a TRY..CATCH and handle both
error 3 or 108 or any other file access specific error as appropriate.
Yup, stay tuned. I wrote the framework before there was TRY...CATCH.
Thanks.
