Subj:   Re: Locking 2 tables

Just add another LOCKING:

     LOCKING TABLE a FOR ACCESS
     LOCKING TABLE b FOR ACCESS
     SELECT

Btw, i would prefer LOCK ROW ACCESS instead:

no need for adding all table names and it automatically upgrades to a table lock when neccessary.

In very old releases there used to be some problems with this approach (in some cases the row lock was upgraded to a table lock with READ instead of ACCESS), but now only some rare combinations in multi statemnet requests might show that behaviour (if at all).
