I tested and found database file is not exclusively locked by a process in that two processes (J instances) can access the same database file concurrently. Does sqlite actually support multi-user access.
in the verb apply=: 4 : 0 exec 'begin transaction;' [...] it does not check for existing transaction, does sqlite support nested transaction? -- regards, bill ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
