if <fs> is already assigned, and then assign it to a non-exist column. it seems that <fs> is still assign to the original column, no exception raised.
i've no idea how could i detect the failure of assgin and raise exception by myself?
thanks and Happy New Year.
ASSIGN structure->('correct_column_name') TO <fs>.
<fs> = ...
ASSIGN structure->('nonexist_column_name') TO <fs>.
<fs> = ... " this will still affect the 'correct_column', not second one.
