    Hello

    Why do I get in tcl 9.0 the following results?

    set l {1 2 3}
    1 2 3
    foreach a $l {puts =$a}
    =1
    =2
    =3
    < foreach a {*}$l {puts =$a}
    =1
    foreach a {*}{1 2 3} {puts =$a}
    =1


    Regards

    It is the expected result (for 9.0 as well as for 8.6).

    Try

    foreach a 1 2 3 {
    puts "=$a"
    puts "=$2"
    }

    This is the foreach synopis

    foreach varlist1 list1 ?varlist2 list2 ...? body

    varlist1 is "a", list1 is "1", varlist2 is "2" and list2 is "3"
