comparing two arrays / array slicing

hi,
I am looking for a smart way to compare two arrays, respective a subset of two arrays;

Interesting enough :
In case that I use array slicing like :
IF arr[[ 1 TO 3 ]] = arr2[[ 1 TO 3]] // array of unsigned int

WX 12 says Hasta la vista
even a arr[[ 1 TO 3 ]] and pressing the return key is enough....

in C we have the memcmp() function like

memcmp(&arr[0], &arr2[0], 3)

atm I use a workaround similar to ;

PROCEDURE _memcmp(arr1, arr2, len is unsigned int)
//dbgAssertion(TypeVar(arr1) = wlArray and TypeVar(arr2) = wlArray )
 
WHEN EXCEPTION IN
	FOR i = 1 TO len
		IF arr1 <> arr2 THEN
			RESULT False 
		END
	END
	RESULT True
DO
	ExceptionEnable()
	RESULT False
END

But I don't like it. Ideas ?

Bjoern...
