Answer / basha
var a-z : this shows error message because it does not have
any numeric suffix
var a1-a5: it diplays variables a1 to a5
i.e it only shows variable ranges
var a--z : it displays a to z it includes variables between
a to z
ex;
data k;
input a b c z;
datalines;
1 2 3 4
5 6 7 8
;

proc print;

Answer / satish kumar.v
IF you have given this
data k;
input a1 a2 a4 a3;
datalines;
1 2 3 4
5 6 7 8
;
proc print;
var a1--a4;
run;
proc print;
var a1-a4;
run;
the order is taken as priority when ever the a4 occurs then
it will stops processing in the case of a1--a4 i.e it will
display only 3 variables (a1 a2 a4) where as in second case
a1-a4 it will display all the 4 variables with 2 records

Your question is not clear, I am assuming a, z as variable
names.

input a--z; is the name range list between a to z.
