There are three things you could do here: 1. Start the racket REPL, use `enter!` to run the program, and then type in your expression. This is very similar to how DrRacket works.
2. Make sure the relevant things are `provide`d by your module, then `require` the module and execute an expression. Here's an example: [samth@huor:~/sw/plt/extra-pkgs/racket-lang-org (master) plt] cat a.rkt #lang racket (define x 1) (provide x) [samth@huor:~/sw/plt/extra-pkgs/racket-lang-org (master) plt] racket -e "(require \"a.rkt\")" -e "(displayln x)" 1 3. Write the program you want as a module which uses `require` to depend on the code you've already written, and then just run that program as `racket program.rkt`. I strongly recommend option 3, but any of them should work for you.
