/sys$common/syshlp/helplib.hlb PASCAL, Predeclared Routines, Null String  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Compaq Pascal provides routines for manipulating null-terminated
  strings.   These  routines use the predeclared type C_STR_T as a
  pointer to a null-terminated  character  string.   The  compiler
  assumes  that  buffers are large enough to hold their values and
  null-terminated  strings  are  actually  terminated  by  a  null
  character.
