(PowerBuilder) HTTP POST JSON and Parse JSON Response

Demonstrates how to send a JSON POST and then parse the JSON response.

Note: This example requires Chilkat v11.0.0 or greater.

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// The JSON response to be parsed looks like this:
// {

//   "CriticalIllnessAmount": 0,
//   "CriticalIllnessResidualAmount": 0,

//   "PolicyFee": 0.00,
//   "PolicyFeeSecondary": 0,
//   "PolicyFeeHidden": 50.00,
//   "PolicyFeeHiddenSecondary": 0
// }

// We can get the floating point numbers as strings.  Then convert to double
// using the appropriate string-to-double conversion for your programming language.
// For example, in C++ use atof.  In C# use Convert.ToDouble.
