dbGet and playing with the database

jkang

dbGet and other database operations seem like they would be very powerful tools. I'm surprised there isn't more reference material on sourcelink for how to use them. I'm slowly traversing through it using trial and error and the appendix in the Encounter Text Command Reference but I'm wondering if there are any articles out there that might be a better tutorial for working with the database inside of Encounter.

    Thanks Kari. I browsed through that tutorial along with the documentation and it cleared up many things. I didn't quite understand the structure of the database (pointers and what the -p option did in particular) and that threw me off.

    One specific problem I'm having atm -- and I was wondering if you could help me out -- is trying to pattern search through a list of coordinates. I want to find (and grab pointers to) rows that exist within a certain range of y locations. E.g. between 490 and 4000 and get their top and bottom boundaries. I tried:

    dbGet top.fPlan.rows.box 490

    at first just to experiment but it returned all of the boxes for every row. Is it possible to search through box coordinates?
