To use SML from a shell, you need to add /cse/courses/misc_lang/axp/sml/bin to your path (in your .cshrc file). Now you can type sml at the shell to get the SML interpreter.
Click on the Start button, and choose the Programs menu. From there, select the Server Apps menu, and finally select SML NJ 109.28. To use the SML interpreter as you would from a shell, choose the run sml-cm option.
You can download and install SML yourself here.
When running SML, you can load the contents of a file by running
- use "file.sml";
which corresponds to (load "file.scm") in Scheme.
