dynamically allocating arrays inside structures

i wonder what's the best way to dynamically allocate arrays inside structures.
well, even a good way would be enough

imagine the following example:

Code: Select all

Structure one
 x.f
 y.f
EndStructure


Structure two
 something.one[#dont_know_how_much]
EndStructure

'#dont_know_how_much' isn't known at start.
the value needed is generated at runtime.

how would i adjust 'something.one' to fit?

hope i explained myself well enough..

tia,
traumatic

I think I know your problem, I have the same too in my app.
There is no way atm to add dimensions to a structure yet, as far as I know.

The best way would be to use a linked list in that case which is much faster and does not need so much memory. But for this way, I have to completely recode my app and this is a very huge work.

If i understand you need to redim the array but as far as i know its not possible on PB until now.

As tranquil says maybe lists are the solution.

Maybe one wish for PB is to manage arrays as other basic does.

But it IS possible to redim an array. Only I don-t know if doing it resets data or not.

yes, using dim you can resize an array and yes, the contents gets deleted.

my problem is the usage of arrays inside structures.
using somearray[] inside a structure isn't a 'real' array one could change with dim, is it?
you also can't work with dim while setting up a structure, can you?

Structures cannot be changed at runtime (logical).
You have to use another way.
