Does it? Or did it do so in some versions? It shouldn't, but it does perform similarly to PACK (create a new table, append, kill the old), the difference being that it appends deleted records as well, and preserves their deleted() status.

The error 1115 description never got updated. Since VFP7 ALTER TABLE generates that error when cursor has long field names. In VFP6 and earlier the field names were silently truncated to 10 characters.
