Aliases%spellRoutineVerifyTargets( )

    This function has specific usefulness within a BlobbieScript used to
implement a spell. The function makes particular use of variables
pre-defined for spell BlobbieScripts and is provided to mimic behaviour
present in the MUD's C source code as provided via #defined MACROS.

This function will verify that the entries in the @targets variable are
still available to receive the effects of the spell. The specific
definition of availability depends on the type of target and the effect
of the spell.
