I haven't been paying a whole lot of attention to the messages about 
typesetting computer programs, but one I read had an interesting idea:  reverse
the typefaces, leaving reserved words in plain face and putting variable and 
procedure names in boldface instead.  (The argument went something like this:  
reserved words are a computer language's fancy idea of punctuation, and besides
not really as important as the variables and such, so why not turn things
around?)  Well, I tried this idea out by typesetting a little procedure from
Jensen and Wirth's Pascal User Manual and Report, and I'm convinced -- it
really looks better!  So, for your perusal, I enclose below a little plainTeX
file with a Pascal procedure to find and print the largest and smallest entries
in an array of n integers.
