The DMCONTROL specification designates the title of the DMCONTROL code file for the database.

The following diagram illustrates the syntax for specifying the DMCONTROL code file title:

<DMCONTROL specification>

── DMCONTROL ── = ──<file title>───────────────────────────────────────┤

Explanation

The file title can include a usercode and an ON <family name> specification. If the DMCONTROL specification is not designated, the default title for the DMCONTROL code file is SYSTEM/DMCONTROL. However, it is recommended that this file title be explicitly specified.

Family substitution occurs at run time for this title.

This file title is contained in the control file. At run time, the title is used to initiate the correct version of the software. Both the usercode of the running task and the family substitution have an effect on which version, if any, of the software is found.

Example

The following statement defines the name of the DMCONTROL code file as SYSTEM/DMCONTROL. The code file is located under the USER1 usercode on the PACK1 pack.

DMCONTROL = (USER1)SYSTEM/DMCONTROL ON PACK1;
