LOOP Statement

LOOP stmts END

The LOOP statement executes stmts repeatedly in an infinite loop. Normally an EXIT statement appears in some IF statement in stmts to exit the loop when some condition becomes TRUE.

Example

The following example prints "Hello" forever.

LOOP
  IO.Put("Hello\n");
END (* LOOP *)

The following code reads from standard input until there is an eof.

LOOP
  IF IO.EOF() EXIT END;
  EVAL IO.GetLine();
END;
