How to delete/reset an array?

[Sam Karli]

Hi,
i have an array used more than once through a subroutine (sort it). The data stored in array varies, so does the length of the array. The problem is that I access/use array length through vardim1(array).

If in a previous use of the subroutine the array was longer, the array stays the same (longest) length, and the sorting algorithm will sort junk into the array.

So I would need resetting/deleting the existing array (of that name).

Is there a sollution for this? (Without splitting the stuff into different macros that will slower running it.)

Just realized that dim can be used multiple times and thus for resetting arrays.

Just a question,

Have you been successful to achieve the same thing for array parameter ?

I don't think you can delete just one array parameter easily.

My understanding and as explained in the other post I think ...

You have to read all of the array values into an new array.
Then reset the original array and then add back all of the values except the one you want.
Effectively you will have deleted the value that you want.
That is about my limit of knowledge with arrays.
I have never actually tried doing this myself.

Hi Barry,

I already have done that and it doesn't work, and I don't know why, so I´m open to suggestions

To Barry,

I have found what is wrong, and I will write it in detail in this link.
