Size Of Arrays

[PureNewbie]

If you don't know in advance, does PureBasic have a method of obtaining the number and range of items in an array? The tools I am used to (VB6, VBScript etc) are LBound and UBound, but PureBasic doesn't seem to have these.

I understand that PureBasic can use linked lists and collections instead of simple one dimensional arrays, so this is probably just me trying to get a job done the wrong way.

Any help (or redirection) would be great.

lbound is always zero for PB arrays.

Rumour has it that a forthcoming version of PB will have a cross-platform function for retrieving ubounds of individual array dimensions. In the meantime you can use PeekL(arrayName()-8 ) to get the total number of elements.

for now either in a macro or however you like it:

Getting the Size of an Array():

Code: Select all

PeekL(@Array() - 8)

What are "collections"? Am I missing something?

Many thanks for the replies, I will give your suggestions a go.

My apologies to Little John - for "collections" read "structures" (too many languages going round and round .......).

Ah, I see. No problem.

a Structure is nothing in opposide to an Array.
you can put structured elements into an array as well as into a List.

the main difference is between Arrays and LLists:
an Array has fixed Dimensions (can be more than one) and fixed order for direct access.
a LList has dynamic size and dynamic order in only one dimension for sequential access.
