The SET IMS Command

Because of the changes introduced in FOCUS Releases 6.8 and 7.0, two versions of the IMS/DB Interface are available. With the new version of the Interface, you have access to features such as comma-delimited FOCPSBs, the XMI server, and the Interface environmental commands described in Interface Environmental Commands.

The syntax is

SET IMS = {NEW|OLD}

where:

NEW

Activates new features introduced in FOCUS Release 6.8 and 7.0. NEW is the default setting in FOCUS Release 7.0.

OLD

Provides access to only those Interface features that were available in FOCUS releases prior to 6.8. OLD was the default setting in FOCUS Release 6.8.

When SET IMS=NEW, you have access to Interface new features such as comma-delimited FOCPSBs, the DBCTL environment (available with IMS 3.1 and up), the XMI server environment, Auto Index Selection, and the Interface environmental commands described in this appendix. When SET IMS=OLD, you invoke the Interface that was available with prior FOCUS releases, and you cannot take advantage of the new features.

If you are not sure which FOCUS release you are running, issue the following command:

? RELEASE

For an explanation of how to determine which IMS setting is actually in effect at any point during your session, see The IMS SET ? Query Command.
