The problem is, if you don't do a skip - or some other command that goes to another record - Visual FoxPro will continue showing the current (deleted) record.

The examples I learned (when learning Visual FoxPro) were something like this (I am recalling from memory):
* After asking the user for confirmation:
delete
skip
if eof()
  go bottom
endif
ThisForm.Refresh()
This should ensure that a valid record is always selected after deleting - unless there is not a single record.

SKIP is better than doing GO BOTTOM or GO TOP from the start, since it leaves the user close to the record he was working on. Otherwise, he will have to search for the position again.
