How define global array in JavaScript inline?

I have a timer procedure where I need to use (and keep alive) an array, but I don't know how to define it globally with inline
If I do: let positions = []; inside the procedure, no error, but the array is empty each time te execution enters the Procedure, if I try to define it outside Procedure, an error tell me: Uncaught ReferenceError: positions is not defined
I tried to put the declaration inside an if to only do in one time, but SpiderBasic think it's not initialized

Can you create a small example code that illustrates your problem?

Code: Select all
Procedure Timer()
Define arraySize
!let positions = [];
!const currentValue = { one: 10.00, two: 20.00 };
!positions.push(currentValue);
!v_arraysize=positions.length;
Debug arraySize
EndProcedure
AddTimer(0, 1000)
BindEvent(#PB_Event_Timer, @Timer())

I need !let positions = []; to be global, to not erase it each time it enters in Time procedure

I was trying with LET and VAR but I didn't know it was possible without anything (my JavaScript is near zero)
Thanks Peter

I tried that first too.
JavaScript is a very flexible, but also dangerous language.
