There are two ways to run a script: as the initial script when the REBOL interpreter is started, or from the do function.
To run a script when starting the interpreter, provide the script name on the command line following the REBOL program name:
As soon as the interpreter initializes, the script is evaluated.
From the do function, provide the script file name or URL as an argument. The file is loaded into the interpreter and evaluated:
do %script.r do http://www.rebol.com/script.r
The do function returns the result of the script when it finishes evaluation.
Note that the script file must include a valid REBOL header.
