The type of an identifier defined in a PARAMETER statement is determined
in exactly the same way as the type of any other identifier.  From
the Standard, page 8-8, lined 53ff:

	If a symbolic name of a constant is not of default
	implied type, its type must be specified by a type-statement
	or IMPLICIT statement prior to its first appearance in a
	PARAMETER statement.

Thus, you should have written:

	integer size
	parameter (size = 10)
	character * (size) string

(Sorry I neglected this on my previous posting.)
