Hello,

I've tried researching this topic but it is still not clear to me what
the correct syntax is, or if this is even possible.

Inside one sub, I would like to call a function in an add-in, but want
it to work if the add-in is not necessarily referenced in the project.

Ex.

str = fct_name( arg1, arg2)

This works if I reference the add-in.

str = (?)fct_name(arg1, arg2)

Isn't there a way to fully qualify this (?) such that the add-in does
not need to be specifically referenced?

Thanks for any input.
Eric
