I'm using Cache SQL and want the ability to choose a specific index.

I've boiled the problem down to one table and simplified the query down to

SELECT *
FROM Registration.PatResp
WHERE SchedApptNum=8450022

SchedApptNum is indexed, but instead of using that column, "Show Plan" indicates that it's looping through the entire Registration.PatResp table on Id (the primary key for the table).

I've done a tune-table with no change.

SQL provides %IGNOREINDEX, which allows me to ignore a specific index, but I don't need that.  I need the reverse - %CHOOSEINDEX so that I can force SQL to use a specific index.

I've been asked to annotate a PDF file (in Intersystems Cache).  That is, take in an existing PDF (printable form with areas for people to write in) and use Cache to update it (automatically fill the fields in).

Does Zen have the ability to set a starting/initial PDF?  I see the ability to define an XML format to write in, but that's not exactly what I need, because that will generate my "answers".

I'd like to overlay my "answers" on top of an original PDF.  Do you know how to do that?

Addendum:
After many hours of research, I came across the FOP.
