Changing variable values during step execution

Variables can be changed during execution with step, project, or permanent scope.

For example, if you launch a project with a project environment named Java that includes a variable JavaVersion = 1.4, and you use .bset to change the value to 1.5, any steps that inherit that project environment get the value 1.5, while any steps that reference the Java environment specifically get the original value of 1.4.

Note that when the system starts a job, it copies the project environment variables to a database record set aside for the job, and refers to this job environment thereafter when getting project default values. If the user modifies the starting values of any project variables when the user starts the job, the values are recorded in the job record.
