This isn't exactly the same question but the answer to one will answer the other: having loaded a data table into JMP, can I determine at a later point in the session where it was loaded from?
I can find this out if I've imported a spreadsheet into a JMP data table, because the path of the spreadsheet is recorded as a table variable, and can be retrieved with:
show(dt << get table variable("Notes"));
However I can't see how to access the same information if the data table was simply saved as a JMP table and then later reloaded. JMP obviously possesses this information, because it knows where to write the file back to if you re-save it. Anyone?
