Peter,
	I believe that even Parameter arguments must be previously,
or implicitly declared.  I bet if you put the statement 
IMPLICIT LOGICAL(a,z)
before your parameter statement the compiler wouldnt like any of them.
Actually this is a good idea (implicit something) maybe using complex
would be even better, it makes misspellings etc easier to find, and
is something I use in all of my progs. notice however it must appear
in every subroutine and function.  So to recap try
	   implicit complex(orlogical)(a,z)
	   integer size
	   parameter (size = 10)
	   etc...
hope this helps
(and is right)
