this doesn't work because APPEND FROM read file's data,
help doc is:
APPEND FROM FileName

not from an alias, then it can't see SET FILTER, SE KEY , INDEX ...
Every reference on the FOR clause it is applied to the alias,
and it is constant because the alias record pointer don't change
during the APPEND execution.

Example,
CREATE CURSOR byby (aa i)
ON ERROR ? MESSAGE(),"command: ",MESSAGE(1)
APPEND FROM DBF("byby")

* error
APPEND FROM byby
