Hi,

Suppose I want to create 2 temporary datasets inside a -forval- loop, with
names indexed by the loop number (i.e., `results0', `results1'). Once I get
outside the loop, I want to append them using -dsconcat-, but since I
defined them inside the loop, they no longer exist.

A more concrete example:

forval k = 0(1)1 {

    tempname memhold
    tempfile results

    postfile `memhold' var1 var2 var3 using `results'`k', replace

    forval y = 1998(1)2002 {
        ...

        post `memhold' (`x') (`y') (`z')
    }

    postclose `memhold'
}

dsconcat `results0' `results1'

Could someone offer a suggestion on how to do this, please? Much thanks.
