Classic ASP
Demonstrates Manual Tool Function Calls

Demonstrates how to do manual tool function calling using Chilkat. This is where your application manually checks for function calls in the AI's response, makes the function calls, and returns the function call results to the AI.

' Create the following JSON to define tool functions available for the AI to use.
' Note: You'll use the following JSON format regardless of the AI provider, whether
' it be ChatGPT, Gemini, Claude, Grok, etc.  Chilkat automatically converts to the required

' In this example, the application is providing two functions the AI may choose to call.
