I need to perform a loop Build Delphi Win32. I need for each iteration to set Project File and Starting Dir. How is better to do this?

Hi Boris\_s,
In the BeforeAction script (see the script editor) of the Build Delphi action place the following code;
Action.ProjectFile = FBVariables.\
Action.StartingDir = FBVariables.\
This will mean that before the Build Delphi action is run it will update the project file and starting directory with the variable values you specify.

Hi, Jason,
