EXECUTE FORMULA should do the trick.
For ($i;1;17)
$s:="ARRAY REAL(aANA_"+String($i)+";0)"
EXECUTE FORMULA($s)
End for

Hi All,
I need to create 20 arrays that have a similar name.
I can do this using the pointers?
I try with this code, but in compiled mode not work.
For ($I;1;17)
$vPoint:=Get pointer("aAna_"+String($I))
ARRAY REAL("aAna_"+String($I);0)
End for
Have suggestions?
Thanks

I would not do this unless there is no other solution for the problem I want to
solve.
Better solutions:
- Pre-declare a number of arrays (Array text(MyArray_001 etc.) and use them by get
pointer (Get pointer ("MyArray_"+string($lCounter))
- On interface level you can address most elements without declaring a process
variable, e.g. Listbox columns.
If you do an EXECUTE FORMULA check this:

1) Use a Two Dimensional Array:
http://doc.4d.com/4Dv16/4D/16.2/Two-dimensional-Arrays.300-3433911.en.html
2) Decide if your arrays are Rows or Columns. The Docs call them Rows. If you decide
your arrays are Columns, then you must REMEMBER the Docs need "translation"
anytime you refer to them.
3) Decide if you will use array zero. If you decide to use array zero, then
you must REMEMBER to Clear it yourself.
That's it.
You will want to fill your arrays, so you may want to pass them to another
method, or perhaps another process, or even another computer (method with
execute-on-server attribute). You will want to declare them. You can declare
20 arrays in 20 lines. Or, see #1.
You may want to display your arrays. If so, you will use a List Box. And your
arrays will be Columns. See #2.
And you may want somewhere to put additional info, that goes with the data when
you pass the arrays, and stays synchronized when your user moves or sorts your
List Box. And once your users see these arrays they will want others. If so,
you will likely re-use your code, your List Box, and your arrays. In which
case, see #3.
HTH,
Spencer

Two dimensional array would be my choice too. Using EXECUTE FORMULA to
"declare" a variable seems ugly, especially in compiled environment…
The Docs call them Rows.
yes, and that drives me nuts, it's 1000 times wrong… Who would say that 'Size
of array' returns the number of *columns* in a mono dimensional array?
• 1D array has 1 column and N rows
• 2D array is a collection of 1D arrays of the same type, each of them is a
column…
If you decide to use array zero, then you must REMEMBER to Clear it yourself.
CLEAR VARIABLE does that… with one exception:
array text($arr;1)
$arr{0}:="123"
clear variable($arr)
assert($arr{0}="") //OK
array text($arr;1;1)
$arr{0}{0}:="123"
clear variable($arr)
assert($arr{0}{0}="") //OK
array text($arr;0;0)
$arr{0}{0}:="123"
clear variable($arr)
assert($arr{0}{0}="") //ko * goToTAOW:=true *
