LFUN
  #include <properties.h>

  mixed SetProp (string name, mixed arg [, int sc])

DESCRIPTION
  Set the value of a property.

  Arguments:
    name: the name of the property to set.
    arg : the value to set.
    sc  : if non-zero, the 'soft property' is set.

  Result:
    The value actually set.

  Using this function automatically takes care if the requested
  property is implemented 'hard' (by a function Set<name>()) or
  'soft' (as a value in a mapping).
  Hardcoded properties may deny a change of the properties value and
  may thus return a value different from 'arg'

EXAMPLE
  #include <properties.h>

  obj->SetProp(P_VALUE, 100)  sets the <obj> value to 100 coins.

IMPLEMENTED
  /std/base
