Release 10.1A: OpenEdge Development:
Progress 4GL Reference

UNLOAD statement

(Windows only)

Unloads a set of environment specifications from the current environment, which might be the registry or an initialization file.

Note: Does not apply to SpeedScript programming.

Syntax

UNLOAD environment [ NO-ERROR ]

environment

A character expression that evaluates to the name of an environment that a prior LOAD statement specified.

NO-ERROR

Directs Progress to suppress any errors that occur in the attempt to unload the environment specifications. After the UNLOAD statement completes, you can check the ERROR-STATUS system handle for information on suppressed errors.

Notes

An application cannot UNLOAD a set of environment specifications until it terminates all windows that use those specifications.
If you UNLOAD the current environment, the default environment becomes the current environment. To define a new current environment, use the USE statement.
Use the UNLOAD statement to clean up memory in applications, such as the User Interface Builder, that build and run other applications.
