How to return a string vector from a custom function?

I am working on a custom function and I would like it to return something like this:

In MCADINCL.H, the only return formats defined are:

// types to be used in declaration of the function's

// arguments and of the return value

#define COMPLEX_SCALAR  1

#define COMPLEX_ARRAY   2

#define STRING 8

There is no STRING_ARRAY, is there a way I can do this?

Something similar is done in this thread: import data with dat file and string

Thanks in advance
