Re: Looking for Skeleton RPG program

The browser does allow to move faster, but loading a lot of records does
take time.  In local networks a couple thousands is fast, but over a
slow link it will be a waste of time. 

Find the optimal balance between "fine selection" and "lots of data"

the excess "in memory" but wouldn't that be because they don't want to be
ground to a halt?

My observation, as a user, is that the browser does not allow you to move
faster; it just makes you *think* you're moving faster.

Move to the web. A very big "sub-file" will take long to load, but then the
browser will allow you to move very fast.

the first 100 rows or so - but ...

They may have eventually changed their approach - we stopped working with

them shortly after that as they decided to "move away from RPG and take
advantage of the speed of Java" - yea - right. Company subsequently went
under in the big banking/insurance crisis of the late 1990s.

Hopefully you gave them a lesson on where clauses.

9,999 is nothing - some years ago a client asked me to help them work out

why the Windows team were constantly complaining about the performance of
the IBM i on remote SQL access. Turned out the idiots were running queries
that returned in excess of 1,000,000 rows!

Wonder how long it would have taken the user to page through that!
