Important: File Corruption Bug in Windows Version of DrScheme 299.200
If you work on a Windows machine, do not insert non-textual elements (e.g., images, boxes, graphical characters) into your Scheme files. There is a bug in v299.200 that corrupts these files, preventing you from re-opening them.
Glasgow Haskell Compiler
To use the interactive Haskell evaluator on the department network, run /course/cs173/bin/ghci . If you want to install the Haskell system on a personal computer, you can download the same version here.
The SWI Prolog system is installed on the CS department network in
/usr/bin/prolog. To load a file, enter its name between
square brackets and single quotes at the prompt, followed by a period.
For example, to load a file called
?- ['types.prolog']. % types.prolog compiled 0.00 sec, 2,124 bytes Yes ?-
Now the definitions from the file are in the database and will be reflected in any queries entered at the prompt.
