-input- is an answer in principle, but useless in practice for your situation.

In practice, if J variables will fit in memory, and J + K variables
will fit in memory, then read in those J + K all at once. Anything
else, e.g. a -merge- with the extra K variables, is likely to be much
more work.

Perhaps I am missing something here...
