Variable Accessors

Vega256

Hey,

So suppose that I have an array of 10 longs and I wanted to access the first byte of the first element. Could I do this?

someLong [10]

someLong [0].byte [0] := someValue

Would be better to just declare an array of 320 bytes?

No, but you can do this:

byte[@someLong[0]][0] := someValue

BTW, I'm not sure why your version isn't allowed. It's a perfectly reasonable syntax.

The compile error says "Variable needs an operator". There may be something else wrong in my code. Instead of immediate data for the indices, though, I do have variables.

I guess you'll need to post your entire program if that gave you an error.

You can use someLong.byte[ 0 ] where the subscript is a byte offset from the beginning of someLong. If you might want to say someLong[ x ].byte[ 2 ], you'd have to use someLong.byte[ x*4+2 ] or someLong.byte[ x<<2+2 ].
