In article <1991Jan20.210328.18087@hoss.unl.edu> 231b3678@fergvax.unl.edu (CS 231 section 2) writes:
   #include <stdio.h>
   main(){printf("hey man!\n");}

   the result is 4424 bytes, OPTIMIZED and all.  How can a HUGE clock compile
   smaller then a printf statement.

If it was a printf *statement* maybe then it would be smaller. Now
however, it is a call to a library routine that depends on C stdio,
which is usually large. Basically your single call to printf drags in
lots and lots of code to handle all kinds of things.

Try this:

	main(){Write(Output(),"Hey man!\n",9);}

The result should be much smaller. However, since you do not use stdio
in the program (Write() is not stdio) you can use the lattice
_tinymain instead. See the library manual, page L264 for usage.
