Try this...

program define atwi
        version 8
        syntax varlist(min = 2 numeric)
        local t : word count `varlist'
        tokenize `varlist'
        forvalues j = 1/`=`t'-1' {
                forvalues k = `=`j'+1'/`t' {
                        generate ``j''x``k'' = ``j''*``k''
                }
