Sorting a user space
Question:
Currently I get a list of jobs, by user, and place that into a user
space. Unfortunately, when I push that list into a UIM interface for
a user to scroll and select from the list is not sorted.
I would like to sort the data in the user space.
Does anyone know of a resource that I can use?
I did not find a sort api anywhere......
My other choices are to sort the list in the uim (can this be done?)
or put the list into a phyical file and do the sort there. I don't
want to do either of those :-(
Answer(s):
You can use the QLGSORT API, or a user index.
I would suggest reading the user space into an overlaying array. Then
you can sort by any field in the array very easily... something like
this...
D USpaceArrDS100DIM(9999)
D UserName 10overlay(USpaceArr:1)
D JobName 10overlay(USpaceArr:10)
etc....
(hope this is right... not at work....)
The size of USpaceArr should be the total of bytes from all the fields
defined using overlay.
This way, you can sort by any subfield using SORTA keeping the data
intact and sequenced. Refer to subfileds as UserName(i) or JobName(i)
as you would any other array element.
Hope this helps!
