Dynamic Memory allocation

[bencooper]

In Liberty Basic how would I implement Dynamic Memory allocation ?
Here I mean to manage array sizes dynamically to handle actual data  requirements so to save storage space?
Are there any in-built function calls to clear arrays and resize arrays as in C++ ?

redim

Are you really hit a memory limit with LB?

EDIT
I tried to allocate single huge array
I made 1e8 -could redim it to 1 and then back 
2e8 allocates but cannot be allocated second time
3e8 dowes not allocate at all
So limit is somewhere here.

But
if I made 1e7 array

t0=time$("ms")
for i = 1 to n
   s=s+a(i)
next
t1=time$("ms")
print "array op loop ";t1-t0

says it took 3 minutes.
My machine is old, but I still think it's very long - I expect for 1e8 not less then 30 minutes, just to single pass through array.

Probably big data needs faster language.

I have not used this and just looked at it myself. May help, hope so.

It would help to know what size of array or data we are talking about. Dim and Redim manage arrays and the space is recovered automatically by garbage collection.

bencooper,
Feel free to head over to the link shown by beetrap. You will find a link to my forum (also linked below) where you will find the Dynamic Array library as well as my Import Architect tool. Start a conversation if you wish, and I can get you headed in the correct direction with one/both.
