I was about to ask in what way, then I realized that the "inner" loop
would have to be recalculated every time the "outer" loop executed. Good
call there. :)

How large is your csv-file? If it is large then probably much time is spent
when transfering the data from your hard drive into memory.

I have few simple questions:
what is happening practically with the memory when I open a file and
start to read it in into a local variable called myvar?
It would be logical for myvar to grow until it reads in the entire file.
My question is:
- does Gambas clear the memory allocations after the myv
felder as STRING[] is a parameter passed into sub
It is no good outside of SUB
What you should do is make your sub
PUBLIC FUNCTION ListeKundeFelder(schlysselnr AS String, felder AS String[]) AS
STRING[]
and return the string[], assigning it to the original felder[]

The problem is not that feld.copy does not copy the array or something like
that, it really returns a NEW deep copy of the array, i.e. a new object.
When you call the function by executing
ldsv.ListeKundeFelder(schlyssel[ls.Index], felder)
you pass the reference to a String[] you want to populate
Thank you everyone, that information is extremely useful. You can also
time several repetitions of the code and compare the results. It seems
declaration and pre computation of variables involved in a For...Next
loop isn't necessary other than for legibility, which is awesome.

Gambas is open source, so you can always look in the source code how
everything is implemented. e.g. look in gbx_exec_loop.c and look for
jump_next.

Kevin,
As far as I found out, it is done only once at the beginning. Just make
a test: set a stop point before the loop, and than make single steps
through the loop watching the local variables.
I use this for getting clear about efficiency from time to time, and I
found it a pretty eye-opener

That was it, Jussi, thanks a lot!
Here we can see what it is good for to know about OOP :-)

The calculation is done only once in the beginning of the loop.
