----boundary-LibPST-iamunique-256865737_-_- Content-type: text/plain Thanks Aubrey. Not sure I like it but thanks. I have adopted the strategy that all procedures that accept vectors or matrices specify their arguments for general forms (i.e. VDesc and MDesc) even when they only want a restricted subset. I let the module context enforce the preconditions. -Doug Aubrey McIntosh wrote: Try this: MODULE PrivTest2; TYPE VDesc = ARRAY OF REAL; V3Desc = ARRAY 3 OF REAL; MDesc = ARRAY OF ARRAY OF REAL; M3Desc = ARRAY 3,3 OF REAL; MTubeDesc = ARRAY 3 OF V3Desc; PROCEDURE Q (IN v: VDesc); BEGIN END Q; PROCEDURE Q3 (IN v: V3Desc); BEGIN END Q3; PROCEDURE Test; VAR mt : MTubeDesc; BEGIN Q(mt[0]); (* works *) Q3 (mt[0]) (*also works*) END Test; END PrivTest2.
