When working on a team development project, you should first adjust the configuration of ZOM for each development environment so that objects from the various environments can be easily identified. The three configuration options of importance here are the environment code, the new keyword, and the changed keyword. You configure ZOM using the ZOMConfig command.

Each development environment should be assigned a unique ZOM environment code. This guarantees all objects are registered with object keys (i.e., ObjectKey property) that are unique across all development environments. In other words, no two objects are ever assigned the same object key even though they might have been created in different development environments.

For example, you could assign environment codes based on your initials, followed by a serial number: “NICK01”. When a developer creates a new environment, the serial number assigned in the environment code could be incremented (e.g., “NICK02”, “NICK03”, and so on.).

If you do not assign an environment code, ZOM generates a random environment code for you. The randomization is designed to make duplicate environment codes unlikely.

There are two other ZOM configuration options that are useful in team development projects. The new keyword option specifies a keyword that is automatically assigned to all newly registered objects. The changed keyword option specifies a keyword that is automatically assigned to all objects you change (e.g., re-create, rename, move, erase, delete, compile, and so on).

The new keyword and changed keyword give you a convenient way to keep track of which objects are new or changed in your environment. You can reset the value of these keywords at any time using the ZOMConfig command and easily remove them from your objects using the standard ZOM key-wording services.

For example, you assign the new keyword and changed keyword to “NewObjs” and “ChangedObjs”, respectively. You are then able to retrieve all new and changed objects in your environment using the keyword selection criteria:

ZOMList +k NewObjs

ZOMList +k ChangedObjs

If you would like to reset your environment so that no objects are flagged as new or changed, use the standard ZOM keywording services:

ZOMSet +k NewObjs ;k NewObjs!

ZOMSet +k ChangedObjs ;k ChangedObjs!

By default, ZOM is configured with the new keyword as “$new” and the changed keyword as “$changed”.
