Any IMS experts out there?

The examples in my book show no difference that I can tell. The description words it like GNP won't "go down" into the hierarchy, staying only at or above the level where it first starts the traversal, but the examples I have contradict that interpretation. (It is not likely I will be able to test it hands-on anytime soon. If I end up using IMS, it will probably be to retrieve existing data rather than change anything on IMS itself. IOW, read-only access.) ________________ oop.ismad.com Edited by tablizer Nov. 9, 2001, 02:56:27 PM EST Expand All History

If unqualified, this call retrieves the next segment in the hierarchical sequence of the database. If SSAs are specified, the call retrieves the next segment that satisfies qualifications specified by the SSAs. GNP get-next-within-parent. This call is like the GN call but is restricted to the subtree of the current parent. (The parent is described in the PCB.) I had a few day introduction to IMS in the 70's sometime.

Just "GN", that has to mean "Grossly Nationalistic", which would make it an especially "patriotic" (or, these last few months, just about any) American. HTH! Christian R.
