 +==== Running programs ==== 
 + 
 +=== Using the interpreter === 
 +Run **ocaml** from the shell prompt, then read the program text with a **#use "filename.ml"** command. All the definitions in the file will be interpreted as if they were entered directly at the current ocaml interpreter prompt.  
 + 
 +=== Compile to bytecode ===  
 +Compile the program using the bytecode compiler **ocamlc**. Then run the resulting **a.out** either using **ocamlrun** command from the shell prompt or directly invoking the **./a.out**

 +<code>
