How on earth can I add (or substract) a complete row of items to an array? I cannot find it in the manual, the examples or in this forum.

I mean, I have
DIM(x,y) but now I want to have an array of (x+10,y+5). How do I add the 10 and 5?
This is turning me nuts.

Thanks a lot.

You can't do that safely - not until update 6. Then you'll be able to resize an array without losing the current contents

you could do

DIM x(1,2)
x(1,1)=10
x(1,2)=10

x(1,1)=x(1,1)+10
x(1,2)=x(1,2)+5


i hope thats what you want... i just finished arrays in the manual. Actually ive just realised thats not what you want! but i hope it helps anyway lol.

No ClownPaint, what I pretend is to add 10 new elements to the array, not just adding a variable or constant to an element. It involves realocating memory and such, so that's why maybe it hasn't implemented yet, though any modern language can take advantage of it.

Anyone knows any other way to make this? Pointers?

I use Array insert at bottom. It works, but only for one dimensional arrays. Its best to avoid having to resize arrays.

You could Undim the array, then Dim it again bigger. Then transfer the data from one to the other using a temporary array.

Or just dim an array that is big enough, and use the elements when you need them

Thanks Emperor, that could work too. Let's see if my *wonderful* system can maintain that. The fact is that I am creating a DIM of TYPE that has several variables in it, and it may be too large. But I'll try that too!
