st:how to transfer a value to another dataset

[Nina YIN <yinnina.ccer@gmail.com>]

Dear all,

I want to define a constant variable in one data-set from a value
generated from another data file. How could I transfer the value
across files?
For example, I -sum ppid cs,
 sum ppid cs

    Variable |       Obs        Mean    Std. Dev.       Min        Max
-------------+--------------------------------------------------------
        ppid |    223566    2294.551    1314.803          1       4544
          cs |    223566      5323.5    3073.242          1      10646

now I got the maximum value of ppid and cs(mppid and mcs).

Then I open another data, and need to generate variables which is
id=_n+mppid, cs=_n+mcs. How could I realize it?

Local can only define the strings. I try to tostring mppid, and local
it , but it failed.

If you have any idea, please help me!

Thank you very much!
