Remarks
Please note that TFunctionParser/TComplexParser won't be developed further as Delphi components.
TFunctionParser 7 is available as Automationserver.
Advantages
- Independent on Delphi versioning
- Accessible by other programming/scripting languages (like C++, C#, VBScript, JavaScript, VBA under MS Office, PHP, Perl, Java, PowerShell, etc.) that support COM/Automation.
- Deployment as single DLL
However, it is necessary to register the server DLL under Windows (Admin privileges required).
