| #### D.2.3.2 A_Z_L Procedure from library `general.lib` (see general_lib). Usage: A_Z_L("a",n); a any letter, n integer (-26<= n <=26, !=0) Return: list of n small (if a is small) or capital (if a is capital) letters, beginning with a, in alphabetical order (or reverse alphabetical order if n<0) Example:
    LIB "general.lib";
    A_Z_L("c",5);
    ==> [1]:
    ==>    c
    ==> [2]:
    ==>    d
    ==> [3]:
    ==>    e
    ==> [4]:
    ==>    f
    ==> [5]:
    ==>    g
    A_Z_L("Z",-5);
    ==> [1]:
    ==>    Z

    ring r;
    list L=list(0,A_Z_L("A",6),list(list("dp",1:6),list("C",0)),ideal(0));
    ring R=ring(L);
    R;
    ==> // coefficients: QQ
    ==> // number of vars : 6
    ==> //        block   1 : ordering dp
