I am just a user but I have in the past used a batch file I am not sure if it will help you but:
Paste the following into notepad and save as a .bat
“C:\Program Files (x86)\Dell\Toad Data Point 3.5\toad.exe” -batch=true %1
Create a new task “Create task” > in the Actions tab you call the batch file then you paste the TAS path into the arguments box.
