Depends what you mean by compress.

If you mean compress in the sense of using a stand-alone program like
some flavour of zip or tar, then yes, you can, but I don't think it
will solve your problem.

If you mean compress in the sense of the Stata command -compress- ,
then no, you can't.

I think you are going to need to read some of the variables in,
-compress-, -save-, etc.
and -merge- saved files. Or ditto, but with observations, not
variables. Or does your analysis really need _all_ the variables?

Incidentally, note how helpful the Stata -cmdname- convention,
commended in the FAQ, is for resolving ambiguity.
