[Gm2] VAR array parameter type compatibility

[SiTex Graphics]

Hi Gaius,

I have a case where GM2 appears to enforce different type
compatibility rules depending on whether a VAR array parameter is a
variable or the parameter in a procedure.

With

TYPE
  fooADDRESS = ADDRESS;

VAR
  foo : ARRAY [0..9] OF fooADDRESS;

GM2 accepts a call to

PROCEDURE DoAddress(VAR a : ARRAY OF ADDRESS)

passing foo.  However, the following call produces a compiler error:

PROCEDURE DoFoo(VAR f : ARRAY OF fooADDRESS);
BEGIN
  DoAddress(f);
END DoFoo;

"'f' cannot be passed to a VAR formal parameter"

Test code attached.  Compile with

gm2 -fiso -c arraytype.mod

-Scott

arraytype.mod
