Moving only one component value into a register AGAL

Question

Hi
Do any of you know if there is any way in AGAL of moving a component value from one register to the other without touching the other components in the register? I notice that the following line...
mov ft1.a, ft0.a
...will also overwrite the rgb components in ft1 with the rgb components from ft0. At least it does on my machine. In other words, specifying components may reorder (swizzle) the components, but doesn't mask them to preserve the value of other components in the destination register. Probably because each register is 128 bits wide, so it's easier for the GPU to just do the operation on all four components anyway. I'm trying to implement the technique described here:

Under "22.2.2 Curves". It requires me to process each color component independently.

"You can't have an HTML form element map to an Oracle PL/SQL procedure parameter that is defined as a TYPE definition"
Sorry, but this is just plain wrong. Passing values to associative arrays (TYPE xxx IS TABLE OF xxx INDEXED BY BINARY_INTEGER) has been possible at least since OAS 4.0.8.
The following simple procedure prints the values passed to it from a form with multiple occurrences of in_val
CREATE OR REPLACE PROCEDURE test_prc (in_val IN owa_util.ident_arr ) IS
BEGIN
for i in in_val.first..in_val.last loop
htp.p(in_val(i));
end loop;
END test_prc;
(owa_util is a SYS package)
As to the original question, it is very hard to say what the problem is without more details about the error that occurs after the migration.
