/* 

   Test of compiling a Pop-11 program to 
     - a saved image 
     - an executable file

   * a) Saved image:
     Run like this to save to a saved image file (.psv):
       ;;;                 .psv file      Pop-11 file       start call
       pop11 %nort mkimage compile_test   compile_test.p    ":main();"

   And run as:
      pop11 +compile_test

   * b) Executable file
     This works on Linux.

     Run:
       ;;;     start call   Pop-11 program    exec file
       popc -e main         compile_test.p -o compile_test
   
     and then
       ./compile_test   

   This Pop-11 program was created by Hakan Kjellerstrand (hakank@bonetmail.com
