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

  The MIN function returns a value (of the same type  as  that  of
  the parameters) that is the minimum value of a specified list of
  parameters.

  Syntax:

     MIN( x1,...,xn )

  The parameters can be any arithmetic type, but must  all  be  of
  the same type.
