You can use sub-directories in your project to hold the Assembler modules and input and output file types. For these files, all assembler input and output locations are controlled by setting specific environment variables.
To set sub-directory locations, you can use the MF370CTL.CFG configuration file, or you can configure environment variables from the user interface or the command prompt, or you can use a combination of both.
For example, you can use the command line or a command file to temporarily override the project file locations set using the configuration file.
