What action does the 'submit' function perform in SAS?

The 'submit' function in SAS is designed to execute the code that has been written in a particular section of a program. When you use this function, it triggers the SAS system to process the commands and statements you've entered, resulting in the execution of the program logic. This allows users to run their programs and obtain results based on the data and procedures specified in their code.

By contrast, the other actions mentioned do not align with the purpose of the 'submit' function. The function does not save the program, edit the syntax, or solely allow viewing of output results. Instead, it is specifically focused on initiating the execution of the code to perform the desired operations within the SAS environment. This distinction is crucial for understanding how to effectively use the submit function in your programming workflow.
