memory allocation error

O/S : Win2000 IDS : 7.31 1. A script runs via dbaccess - dbaccess dbname script.sql 2. The script contains drop table, create table, load, create index statements. 3. the following error appears during a create index statement : 212: Cannot add index. 116: ISAM error: cannot allocate memory. Any ideas what can be done to solve the problem? The problem does not occur if the user runs the script with sqleditor. Any help appreciated.
