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

  The DBLE function converts the parameter and returns its  DOUBLE
  equivalent.

  Syntax:

     DBLE( x )

  The parameter 'x' must be of an arithmetic type.  The  value  of
  'x'   must   not   be   too   large   to  be  represented  by  a
  double-precision number.
