/sys$common/syshlp/helplib.hlb PASCAL, Statements, Empty Stmt  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The empty statement causes no action to  occur  other  than  the
  advancement of program flow to the next statement.

  To use the empty statement, place a semicolon where the language
  syntax calls for a statement.
