.tset env <EnvironGroup> "<VariableName>=<DesiredValue>"
The .tset command changes project settings temporarily during a
step.
- Use the env paramet to specify the environment in which
to add or change variable values. You can use .tset to set a variable
that does not yet exist. The values set by the .tset command are written
to the job record. They do not update the database record for the
environment set. Later jobs are not affected by the changes.
The .tset changes take effect in the current step. It takes effect
for all commands in the step. It is also in effect for any Inline
specified for the step.
