EBCDIC ARRAY E [0:11];
REPLACE E BY "HELLO WORLD!";
WHILE TRUE DO
  BEGIN
  WRITE (F, *, E);
  END;
END.

Program Notes

This program has NOT been tested due to the inability to locate the necessary compiler. It is posted here just to give you an example of what ALGOL source code looks like. Compare it to the other example listed to see the syntactic differences that exist in the language.
