Accessing to variable

Hi to all, I'm creating a my own debugger using Delphi XE7 and Fast Script 1.9 and I need to be able to access the variables declared within procedures
in the script.

Below the example

unit Unit1;

interface

uses

FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs, FMX.fs_synmemo,

If I wish to access (i.e. to variable 'X') declared inside the script the compiler return Variable Unkown.

Could you please help me?

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
