concatenating 10 data sets with same name variable with different lengths

[christine1]

hello.

i have ten datasets (z1-z10). they all have a variable named "group". the variable length varies in the ten datasets from 2 to 6.

is there a way i can concatenate all 10 datasets and have the "group" variable length be 6 in the final dataset without any data being truncated?

many thanks.

What about this:

data want;
length group $10.;
set z1-z10;
run;

proc sql;
create table want as
 select * from z1
union all corr
 select * from z2
union all corr
............
 select * from z10
;
quit;
