Take a look at the ALTER TABLE command:
* create demo cursor with autoinc field
CREATE CURSOR test (id I autoinc)
INSERT INTO test VALUES (10) && error
* remove autoinc feature
ALTER TABLE test alter COLUMN id I
INSERT INTO test VALUES (10) && no problem
* turn autoinc on and specify a new start value
ALTER TABLE test alter COLUMN id I AUTOINC NEXTVALUE 11
