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

  The SUCC function returns the value that succeeds the  parameter
  according to the parameter's data type.

  Syntax:

     SUCC( x )

  The parameter 'x' can be of any  ordinal  type;  however,  there
  must be a successor value for 'x' in the type.
