Simple way to wrap call to FM script into custom function

Hi

I need to implement a change of barcode plugin in a database, in order to move from 32 to 64 bit.

Currently we use SFR barcode plugin. The field for the barcode image is an unstored calculation, calling thar barcode function.

I would like to use Geist Barcode Generator.

Is there a simple way to wrap the script "Render Barcode as Base 64 ( dataToEncode )" into a custom function, so it can be used just like sfrbc_Barcode( Barcode ) .

I thought using BaseElements function "BE_ExecuteScript ( scriptName {; fileName ; parameter } )" but it does not return script result directly to be used.

Ideas and suggestion would be appreciateed :-)
