Can I use your code separate from Apache? I assume I can. If so, it would be GREAT. As my wading through Fileman is about as fun decompiling assembly code. I have been "decompiling" it from its current "paragraph-all-on-one-LONG-line" format into a more modern one-step-on-one-line format. Then I can use my debugger to step through the code and work on understanding what it is doing. Then I would figure out how to make it a quiet function (no user interaction). It would ne nice to avoid all that.
It looks like you are using a "iterater" approach. I learned about this briefly when studying some of the standard libararies for c++. It was a different way of doing things then I was used to (i.e. compared to Borland's VCL).
But I don't mind learning to use your code, if I can make it work at my site.
By the way, you guys seem to have a buch of great code. Do you have a programer's reference that gives an overview of your library, and then details of the API's?
Thanks

I too believe that there is a need for a generic search capability that is not tied to the
old roll-and-scroll user interface.
Here is a little bit of info on a general database query capability included in M2Web
http://vista.vmth.ucdavis.edu/notebook/index/26.html
This makes use of a relatively simple but general iteration object that covers a large
class of MUMPS data structures, including pretty much all Fileman data to any depth of
subfile and cross references, including linked cross references.
(see http://vista.vmth.ucdavis.edu/rtn/iterator.html)
Here is an example of use of an iteration object (kexample) for Kevin's example:
;-- kfilter is a filter condition (or screen), to be evaluated as IF @kfilter
; This variable is just a convenience for constructing kspec.
; It is the essential condition of Kevin's example search in context
; of subfile 50.6814 (ACTIVE INGREDIENTS).
; The variable name "ActvIngr" was derived from the Fileman field name.
; Its characteristics beyond those defined by Fileman are stored in
; ^view(50.6814,"var","ActvIngr").
; The MUMPS code to define it and ActvIngr("Name") will be generated when kspec
; is parsed by new^iterator
;
n kfilter s kfilter="ActvIngr(""Name"")[""ACETAMINOPHEN"""
;
;-- kspec is essentially a global reference with embedded iteration variables
; It introduces the iteration variables VaPrdNo and ActIngNo (and ActvIngr
; from kfilter). These names are also defined in ^view.
; Using variable names defined in ^view is not necessary to the general
; iteration except that it enables the automatic generation of supporting
; code for the simple _expression_ of potentially complex filter conditions.
;
n kspec s kspec="^PSNDF(50.68;VaPrdNo;2;ActIngNo:0:%:"_kfilter
;
;-- kexample will be defined here as an iteration object based on kspec
;
n kexample d new^iterator(.kexample,kspec,50.6814)
;
;-- now the actual iteration
;
n VaPrdNo,ActIngNo,ActvIngr ;the iteration variables
n item f item=1:1 d step^iterator(.kexample) q:kexample="" d whatever
Also, here is a related web based query that lists drugs where "ACETAMINOPHEN" is
contained in the ACTIVE INGREDIENTS (multiple) but not in the NAME.
(http://vista.vmth.ucdavis.edu/query?dbfile=50.68&index=VaPrdNo&filter=ActvIngr%5B%22ACETAMINOPHEN%22%2CName'%5B%22ACETAMINOPHEN%22&format=INGREDIENTS&limit=200 )
After decoding the URL, the filter parameter is a list of MUMPS conditional expressions
that can be used as the indirect argument of an IF command
filter = ActvIngr["ACETAMINOPHEN",Name'["ACETAMINOPHEN"
