din.getc has something in its buffer already (the newline from 
when you hit enter after readf - it uses the number but left the 
line), so it doesn't have to wait.

Simplest fix is to read two lines at the end:


         writeln("Result: ", result);
         readln(); // skip past the enter left from second number
         readln(); // wait for the user to hit enter again to exit


(I'm using readln instead of din so you can just use std.stdio 
alone)
