Looking for Example of How to Use %SQL.Export.Mgr Export Method

https://docs.intersystems.com/irislatest/csp/documatic/%25CSP.Documatic....

method Export(savertn As %Boolean = 0) [ Language = objectscript ]

I am looking to export table to a text file in a programmatic way. I am not familiar with this class and how to invoke a "savertn" as input here.

Essentially I would like to Export Table (SELECT * FROM Table) and save it as a text file locally on Linux server. Is there any examples out there of that? Perhaps I need to save the query output to a global and then pass that input to the export?

Thanks,

James
