Hello Maoyang,

   You can also do the following


    foreach var of varlist * {
        command referring to `v'
                                     }

there is one problem with this program, if there are some variables are
string variables, and the command need to deal with only non-string ones,
you should add a capture to the command, e.g.

    foreach var of varlist * {
        capture replace `v'=`v'*`v'
                                     }


or simply list the variable names:

   foreach var in var1 var2 ... varn {
        capture replace `v'=`v'*`v'
                                     }
