One option is a temporary work file. If you go that route, make the
file static, rather than dynamic and size it appropriately.
Write the records, select the file by the key, read each record and
delete it as you go along. Or select it, save list, get list, process
list, get list, delete file (using list).
And if you're sharing the application among users, use the @userno as
the leading part of the key. Even if you're not sharing the app, use
the @userno, so that when you do share the work file later on you
don't have to recode the app...
