Thank you for the answer and the example... I didn't know there was such a
thing as a variable dictionary, but It looks like that may work for me, I'll
give it a try!

Hi all! It's my first answer to the mailing list, hopefully I won't screw
anything up.

You might want to try using generic dictionaries. E.g. like this:
program Project1;
uses
SysUtils, Generics.Collections;
type
TVariableDictionary = specialize TDictionary<String, PWord>;
var
MyDictionary: TVariableDictionary;
MyVariable1: Word;
begin
MyDictionary := TVariableDictionary.Create;
MyDictionary.Add('MyVariable1', @MyVariable1);
MyDictionary['MyVariable1']^ := 100;
WriteLn(MyVariable1);
WriteLn(MyDictionary['MyVariable1']^);
FreeAndNil(MyDictionary);
end.
If you need to address variables of different type, try Variants (
https://wiki.freepascal.org/Variant ).
