I am actually working on an addin to do this. However, the DLL provided by NI requires, for some of the functions, that an array of strings be passed back... currently, JMP does not offer this support in its DLL package... only an array of doubles can be passed. So, it is currently necessary to write a separate DLL as a go-between, to work around this. I am working on this, but it is a learning process for me... I am currently working my way through K&R as it has been a LONG time since I used C.
So, if I can get this to work, we'll have something... but not in the immediate future, unfortunately.
In the meantime, interested users should add "increased support for arrays in JMP's DLL capabilities" to the development wish list!
Cheers,
Brady
