could ask difference between following 2 coding styles? first 1 read xilinx sample code. second, read book teaching vhdl. 1. signal: register std_logic； signal: output std_logic; process (clk) begin if rising_edge(clk) register <= outside_signal ; end if; end process; output <= register; 2. signal: register_reg std_logic; signal: register_next std_logic; signal: output std_logic; process (clk) begin if rising_edge(clk) register_reg <= register_next; end if; end process; register_next<=outside_signal; output <= register_reg; thank much. the obvious difference intermediate signal register_next declared , driven outside_signal signal, instead of using outside_signal directly in process. the simple answer there no functional difference. (complex answer register_next<=outside_signal delays signal delta delay (not actual time delay), delta delay typically not visible don't worr...

how create named substack background livecode? the livecode dictionary has entry create stack with examples create stack "test" or create stack field 3 background "standard navigation" there no single command create substack. instead need create mainstack, , change it's mainstack property other stack make substack of one. example: create stack "my new stack" set mainstack of "my new stack" "some existing stack" see mainstack property, mainstacks function , mainstackchanged message in dictionary. there way achieve goal, setting mainstack of templatestack (see templatestack object in dictionary): set mainstack of templatestack "some existing stack" create stack "my new stack"

i've got latest xcode xcode 4.6, , have problem: nsarray *array = @[@[@"a",@"b"]]; nslog(@"%d", array[0].count); before run it, xcode told me "property 'count' not found on object of type 'id'". but if change to nslog(@"%d", [array[0] count]); then, fine. so question is, why can't obj-c process two_d_array[index].count ? looks @ docs nsarray . there no count property. in fact, there no properties @ nsarray . when use property syntax non-property method, compiler deal ok if have object of specific type , there method of same name. in case have id . compiler can't safely work out attempt access count property should converted call count method.
