Are data items exposed as environment variables writable or read-only?

Data items exposed as environment variables in Blue Prism are indeed read-only. When you expose data items in Blue Prism, they are made available for use in the environment, allowing process or object instances to access the data. However, the underlying nature of environment variables is that they do not allow for modifications during runtime.

This read-only characteristic ensures consistency and stability in processes, as it prevents unintended changes to the data in use. It also facilitates better control and predictability in automation workflows, safeguarding the integrity of the information being utilized.

Understanding this functionality is crucial for determining how data is passed and manipulated across different components of Blue Prism. Thus, it is important for users to be aware that while data can be read from environment variables, they cannot be altered, which is pivotal for maintaining order and accuracy in automated processes.
