Array initialization

[ancp]

I apologize for propably asking a old question once more - I could not find... Is possible to fast initialize array, like:

Dim $aItems[600] = 0xC1

instead of

Dim $aItems[600]
for $i = 0 to ubound($aItems) - 1
    $aItems[$i]  = 0xC1
next

And one subquestion. Are math and bitwise operations with hexadecimal values faster than decimal values?

$var = BitOR($aItem[$i], BitAND($var, 0x1F), 1))

vs

$var = BitOR($aItem[$i], BitAND($var, 31), 1))

Thanks in advance

ancp,

1. No. You either use a loop or you have to do this:

Dim $aItems[600] = [0xC1, 0xC1, 0xC1, ...another 596 elements..., 0xC1]

which is MUCH longer!

By the way, try not to use Dim. It is better practice to specifically scope your variables with Global/Local instead.

2. Given the relative slowness of AutoIt, I cannot believe it makes any difference which you use unless you have a seriously large number of such lines in your script - but I am quite prepared to be proved wrong!

Thanks Melba, I understand.

Not much of a big numbers, but many of bitwise operations. I understand that AutoIt is not very fast but it's very comfortable

thank you for the reply.
