I just purchased <span style="text-decoration: underline;"><span>Realm of Racket</span></span> and am working my way through it. Although I've been programming for 30+ years, most of that has been with procedural languages (MUMPS, FORTRAN and COBOL) on character-based medical information systems (i.e. reports, EDI and utilities). This is one of my first attempts at GUI and functional programming and I'm enjoying it a lot. Thanks to the creators of Racket and Scheme!</div><div><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif; background-color: transparent; font-style: normal;">I'd like to ask some questions as I go through the book.</div><div style="color: rgb(0,

What % of the book deals with non-Scheme issues? In the GUI version of Guess My Number many of the functions/procedures have an argument of w, which I understand to be world. Why is world the argument instead of, say, interval?</div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: HelveticaNeue,Helvetica
