Hi all

VFP not allowing me the last line of the following code (message 'File must to be o[en exclusive'):

if used ('logs1')
use in logs1
endif
use log again in 0 alias logs1
use(dbf('logs1')) in 0 again alias ddde
use in logs1
use (dbf('ddde')) in 0 again alias logs1
use in ddde
alter table logs1 add column schoolname c(3)

.
I used to use withis way, what happened now?
Thank you
