I don't have a copy of SICP handy (I guess I can just tear up my  
Schemer Membership Card right now...), but "begin" seems to me to be  
the natural choice to express what you want; it's true that there are  
other constructs that behave in a begin-like way, and in fact you can  
write begin as a function (for a fixed number of arguments) quite  
easily, but I would suggest just using 'begin', especially as you've  
been through HtDP already.
