Troi Serial Plug-in 3.0


FileMaker Pro 16 to 19


Important: always use this function to determine if the plug-in is loaded. If the plug-in is not loaded use of external functions may result in data loss, as FileMaker will return a question mark from any external function that is not loaded.


Serial_Version ( "" )

will for example return “Serial Plug-in 6.0”

Example 2

Serial_Version ( "-GetVersionNumber" )

will return 6000 for version 6.0

Serial_Version ( "-GetVersionNumber" )

will return 6510 for a possible future version 6.5.1

So for example to use a feature introduced with version 5.0 test if the result is equal or greater than 5000.
