Open other program and use extra functions there

Hey everybody,

I have a quite specific question. I already know how to open a different program and file using the SHELL command. This is what I have so far :

Public Sub OpenPythagoras()
    Dim f As Variant
    Dim Path As String
    Dim File As String
    Dim x As Double
    Dim y As Double
    

    Path = "C:\Program Files\Pythagoras\pythagoras.exe"
    File = "L:\Grondbeleid\Algemeen\GIS Dendermonde/GIS-poging 1.pyt"

    f = Shell(Path + " " + File, vbNormalFocus)
    
    
    x = ActiveCell.Value
    y = ActiveCell.Offset(, 1).Value

the x and y are coordinates. And my question to you guys is if there might be a way to open my file and let that program zoom to those coördinates.

So my excel file contains a numer of coördinates together with extra info about those places. I want something that allows me to select the coördinates and my program with the map opens up and it zooms to those coörds. If it's impossible to do everything directly from excel maybe the key will be to add a vba macro in that software that makes me select the coords in the excel file and zooms to it ...
