Depends how VarGet is implemented. If it's implemented as O(1) then it should work. A hash should achieve best case of O(1).

Subject: [amibroker] Re: Is there a hash table or dictionary structure accessible from AFL?
Can you use dynamic AFL variables to achieve what you want?
value = 10;
VarSet("myKey", value );
newValue = VarGet( "myKey" );
As for performance, maybe Tomasz can answer what the "order of" the algorithm is (e.g. O(log n), O(n) )?

The collection is sufficiently large that it would benefit from being stored in a data structure with constant lookup time. Has anyone implemented this in AFL or through a plugin?
