Jordah,

I assume what you really want to do here is move key and data from one 
table to another.  

Here's a suggestion:

I would create two sequences, maybe keys and data.  I would also 
determine the largest amount of data you could store temporarily before 
you run out of memory.  Then I would move a block (say 100 records) at a 
time from the source table to your keys and data sequences, switch to 
the target table and move the keys and data sequences to the target 
table.  Then clear the keys and data sequences for the next block.  You 
would, of course, need to retain the last record number you got from the 
source table so when you switched back to the source table you could 
pick up where you left off.  Sorry, I don't have code examples, this is 
really just a theory.

I think what you're frustrated over is the fact that you can only refer 
to one table in one database at a time.  However, the intent of EDS was 
to be simple to use.  That it is, but at the same time you sometimes 
have to be creative in how to accomplish what you're after.
