DrRacket (aka DrScheme) Basics

The following are instructions for the Ryon Lab's Linux environment:

Via the graphical user interface (GUI):

1. Open the folder on your desktop that is labeled with your NetID ("netID's Home")
2. Right-click on an open spot in the folder window and select "Create Folder".
3. Name the new folder (directory) "Comp211".
4. Double-click the Comp211 folder to open it and inside of it, create another folder (a sub-folder) called "Lab00".
5. Save all your Lab00 work to this folder. For submitting homeworks, see the Owlspace page for Comp 211.

Via a command line:

1. Open a terminal (right click anywhere on the desktop and select "Open Terminal").
2. Make a new folder (directory) called Comp211, for this course. The command is for making a new folder on Linux is mkdir.
3. Make a sub-folder in Comp211 called Labs.
4. Make a sub-folder in Labs called Lab00. Save all your Lab00 work to this folder. For submitting homeworks, see the Owlspace page for Comp 211.
5. Start DrSchemeby typing the command drscheme.
   #If this is the first time you've run DrScheme, it will ask you your preferred language, and the Scheme language level; the latter should be "Beginning Student with List Abbreviations". This language level provides the expected set of primitive operations and enables DrSchemeto reject "legal" Scheme constructions that are not part of our introductory dialect.
